Summary:
Previously we computed the list of nodes that need to be notified about layout changes using a list of mutation instructions. That was fine, but that's not really compatible with some other changes that I plan to make, so I decided to change it (make it better).
Besides the better design (debatable; fewer dependencies to unrelated moving pieces), here is why I believe the new way is more performant:
* The new approach has no `dynamic_casts`, whereas the previous has tons of them (two per a mutation). If a `dynamic_cast` takes 10 ns, for 500 nodes it can take up to 5ms only for casts. (Non-scientific assumption.)
* After removing dependency to mutation instruction, we can enable flattening for views which have `onLayout` event.

Furthermore, this change can (in the absence of tracking bits) avoid less specialized templates dealing with refs, and to dynamic dispatch as a consequence.

Summary:
Different frameworks use different kinds of floats, optional floats, and floats with assigned unit names. All those approaches use different ways to represent undefined and empty values. To deal with it we need to have some helper functions.
So, this diff changes some ways that we convert some corner values (like NaN and empty value). That change is motivated by recent personal discoveries in this field that shifted my vision on that. E.g. ComponentKit does not use `CGFloatMax` value as `Infinite` value. UIKit is also (surprisingly to me) okay with using `Infitite` instead of `CGFloatMax`. And, in general, seems using really conceptually appropriate values (instead of UIKit-inspired ones) it's the right thing to do.

Summary:
We don't need to have those constants because this functionality is available in STL via `std::numeric_limits<YourParticularFloatType>::infinity()` (or `::min()` and `::max()`).
At the same time usage of `kFloatMax` was replaced with `Infinity` (which is a different value). Using `max` instead of `Infinity` was an attempt to mimic iOS/UIKit model where `Infinity` and `NaN` values usually are not being used. However, now this does not seem like a good idea. This concept is not used anywhere else (even in CK which is totally incompatible with it) and de-facto in RN we use it only in few places. So, let's use Infinity in places where it's logically appropriate.

Summary:

Adds `YGStyle::ValueRepr` to make code depending on the actual type easier to write.
So far, we have treated `yoga::detail::CompactValue` as an implementation detail, and that’s what it’s supposed to stay.
React Native Fabric has one value conversion overload that depends on that type, though, and used `decltype(YGStyle{}.margin()[0])` until now.
That’s problematic for two reasons:
- we want to constrain the parameter of `operator[](...)` to enum types, making the `0` unsuitable
- we want to return the non-const overload of the operator to return a custom `Ref` type, which is not the type needed by Fabric.
Making the storage type explicit allows to write more forward-compatible code.

All accessors have a `const` version that allows direct access via `const&`. For mutation, bit fields are wrapped with a custom reference object.

If you call into a Java method (from C++ using JNI) that raises an exception, the JNI call won't actually raise a C++ error. Instead, the `JNIEnv` will record the pending Java exception and the C++ will continue executing as normal. This is bad because the next time you call into JNI, the app will actually crash, unless you explicitly cleared the exception using `JNIEnv::ExceptionClear()` before the JNI call.
With respect to TurboModules, we need to make sure that RedBoxes show up whenever a native methods raise an exception. We also don't want the app to crash when a JNI method call fails because of a raised exception. Therefore, in this diff, I raise a C++ exception if `JNIEnv::ExceptionCheck()` is true.

This diff replaces all MountItem classes with a bunch of static C functions that do the same job as classes did.
Seems, originally we overestimated the complexity of MountItem classes and that they ended up being notably trivial. Now, maintaining that even longer would mean paying for abstractions and allocations that we don't really need and writing a lot of tedious code.
Besides that, the one particular change that will be introduced in the coming diffs is not particularly fit very well in the existing class-based model.
This change also should save us many hundreds of allocations and atomic counters bumps, so maybe we can get a millisecond-or-two win.
This diff does not introduce any practical behavioral/logical changes in the mounting layer.

Previously the diffing algorithm inserted views top-down, now it insert views bottom-up (same order as previous version of RN).
Let say we need to create the following tree:
```
A --> B --> C
|
| --> D
```
Before, the diffing algorithm created the following list of instructions:
```
insert(A, B, 0)
insert(B, C, 0)
insert(B, D, 1)
```
After this diff, the insert instructions are going to be:
```
insert(B, C, 0)
insert(B, D, 1)
insert(A, B, 0)
```

This allows an unsupported component to be rendered as a "unimplemented view" for better visualization of which component is missing. It is off by default, but configurable in the component factory.
For now, the layout simply follows regular <View />, which means the width/height etc is based on the react component styling. The side effect is that components with 0 height/width won't show up at all.

Summary:
For props that expects a struct/object value, like scrollView's contentInset, not all keys may be present. For example:
```
<ScrollView ... contentInset={{top: 10}} />
```
In this example, `left`, `bottom`, and `right` should just default to 0 (or whatever the default is in the platform). Before this fix, an exception occured when calling `fromRawValue()` because it is assuming all 4 keys are present in the prop bag. However, only `top` key was present in this example.
To fix this, we have to loop through the available keys in the prop bag, then assign the values accordingly.

Summary:
Informal `DebugStringConvertible` interface serves the same purpose as `DebugStringConvertible` abstract class (providing universal pretty-printing interface) but relies on C++ static overloading instead of virtual dispatch.
This approach has some advantages and disadvantages:
Pros:
* It's more clear and scoped. It's simpler to implement debug-printing functionality aside of normal production code.
* It's more composable.
* It allows print types that are not classes.
* For some classes using `DebugStringConvertible` means that we have to use virtual inheritance (which might be undesirable and affect *production* performance (if a compiler isn't smart enough to remove empty base class).
* For some highly lean classes (that designed to be as small as possible) adding base (even empty-in-prod) classes kinda... smells.
Cons:
The particular implementations cannot rely on dynamic dispatch which can complicate printing classes with meaningful differences between sampling classes (e.g. ShadowNode subclasses). That's why we don't remove `DebugStringConvertible` class yet.

Summary:
If a NativeModule method requires an optional boolean argument, our codegen translates those optional booleans into `NSNumber*` instead of `BOOL`. The reason why is probably because this is the closest object analogue to `BOOL` in Objective C. The same boxing occurs with numbers. If the type of a number argument in JavaScript is optional, we'll map it to the `NSNumber*` Objective C type instead of `double`. Our existing TurboModules argument conversion code would not take this behaviour into account. Therefore, we'd try to insert a `BOOL` where the `NSInvocation` would expect a `NSNumber*`. This, in turn, would cause the app to crash. (Why would it crash at the point of NSInvocation retainArguments, I'm still not sure).
Our flow typechecking ensures that if the type of a method argument is a boolean, we pass in a boolean. Therefore, on the Native side, if we detect a boolean, we can check the type of the Native argument to see whether we should box the primitive. If the native argument type is an object, then we know it has to be an `NSNumber*` in both cases, so we simply wrap the `BOOL` or `double` in a `NSNumber*`.

Summary:
In D14571128, we made it so that when a JS object's property was `undefined`, we wouldn't insert that property into the corresponding NSDictionary. Here are two important observations about that diff:
1. ALL JS `null`s were now being converted to `NSNull`, and JS `undefined`s were now being converted to `nil`.
2. If a JS object's property was explicitly `null`, then we'd insert `NSNull` into the corresponding dictionary.
Considering that when a property doesn't exist in a `NSDictionary`, property access returns `nil`, I've made it so that if a JS object's property is either `null` or `undefined`, then we simply do not insert it in the corresponding `NSDictionary`. Also, I've reverted #1 and made it so that `undefined` and `null` always map to the ObjC `nil`.
This shouldn't unfix the problem that D14571128 was trying to fix.
Here's my understanding of the problem that D14571128 was trying to fix (to make sure I'm not breaking something by this diff).
This method was invoked from JS.
```
RCT_EXPORT_METHOD(logEvents:(NSDictionary *)events)
{
RCTAssert(events, @"You should provide events for logger");
[[NSNotificationCenter defaultCenter] postNotificationName:@"FBReactPerfLoggerDidReceiveEventsNotification"
object:nil
userInfo:@{@"FBReactPerfLoggerUserInfoPerfEventsKey" : [events copy]}];
}
```
The above dispatch calls into this method, which appends `events` into `_pendingJSPerfEvents`.
```
- (void)reactPerfLoggerDidReceiveEvents:(NSNotification *)notification
{
NSDictionary *events = notification.userInfo[@"FBReactPerfLoggerUserInfoPerfEventsKey"];
if (events) {
dispatch_async(_eventQueue, ^{
if (self->_sessionData.perfLoggerFlagId != nil) {
if ([self processJSPerfEvents:events]) {
[self reportMetricsIfFinished];
}
} else {
[self->_pendingJSPerfEvents addObject:events];
}
});
}
}
```
Then, in `_processJSPerfEvents`, we do the following (link: https://fburl.com/tr4wr2a7):
```
NSNumber *actionId = events[@"actionId"];
if (actionId) {
self->_sessionData.actionId = actionId;
}
```
So, if `undefined` or `null` was passed in as the `actionId` property of the `events` JS object in `FBReactPerformanceLogger logEvents:`, then we'd default the `NSDictionary` to have `NSNull` in the corresponding property. This is bad because we had this line in FBReactWildePerfLogger (link: https://fburl.com/2nsywl2n): `actionId ? [actionId shortValue] : PerfLoggerActions.SUCCESS`. Essentially, this is the same problem that my diff is trying to fix.

Summary:
With our current infra, we support automatic conversion of method arguments using `RCTConvert`.
```
RCT_EXPORT_METHOD(foo:(RCTSound*) sound)
{
//...
}
```
```
interface RCTConvert (RCTSound)
+ (RCTSound *) RCTSound: (NSDictionary *) dict;
end
implementation RCTConvert (RCTSound)
+ (RCTSound *) RCTSound: (NSDictionary *) dict
{
//...
}
end
```
```
export interface Spec extends TurboModule {
+foo: (dict: Object) => void,
}
```
With this setup, when we call the foo method on the TurboModule in JS, we'd first convert `dict` from a JS Object to an `NSDictionary`. Then, because the `foo` method has an argument of type`RCTSound*`, and because `RCTConvert` has a method called `RCTSound`, before we invoke the `foo` NativeModule native method, we first convert the `NSDictionary` to `RCTSound` using `[RCTConvert RCTSound:obj]`. Essentially, if an argument type of a TurboModule method is neither a primitive type nor a struct (i.e: is an identifier), and it corresponds to a selector on `RCTConvert`, we call `[RCTConvert argumentType:obj]` to convert `obj` to the type `argumentType` before passing in `obj` as an argument to the NativeModule method call.
**Note:** I originally planned on using `NSMethodSignature` to get the argument types. Unfortunately, while the Objective C Runtime lets us know that the type is an identifier, it doesn't inform us which identifier it is. In other words, at runtime, we can't determine whether identifier represents `RCTSound *` or some other Objective C class. I figure this also the reason why the old code relies on the `RCT_EXPORT_METHOD` macros to implement this very same feature: https://git.io/fjJsC. It uses `NSMethodSignature` to switch on the argument type, and then uses the `RCTMethodInfo` struct to parse the argument type name, from which it constructs the RCTConvert selector.
One caveat of the current solution is that it won't work work unless we decorate our TurboModule methods with `RCT_EXPORT_METHOD`.

Summary:
Before invoking TurboModule ObjC methods, we loop through all the arguments and transform them from `jsi::Value` to ObjC data structures. `jsi::Value`s that represent JS Objects get converted to `NSDictionary`s in ObjC. This isn't good enough because `NSDictionary` isn't typed. What we really need is a C/C++ struct that represents the type of the JS Object.
Therefore, for every argument of a TurboModule method that is a JS Object, this diff allows you to specify a method on `RCTCxxConvert` (which you have to declare and implement) that transforms that type of JS Object into something else. Basically, with the changes in this diff, we'll be able to transform JS Objects into C++ struct instances, which gives us type safety for JS Object method argumetns to TurboModule functions.
I modified the codegen to also create a mapping from NativeModule method name => argument num => `RCTCxxModule` conversion selector. This way, the FB codegen that generates the `RCTCxxConversion` function also informs our TurboModule system which conversion function to use before we call the method requiring complex argument. I just had to extend the `ObjCTurboModule` class to accomplish this.
The old system relies on the additional method generated by `RCT_EXPORT_METHOD` macro. It takes the written code, does string processing on it to parse the type of the struct arguments, and then replaces all instances of `::` with `_`. Super hacky. I didn't take this approach because it seemed unnecessarily hacky brittle.
The other approach I considered was to try to use reflection to infer the type of the struct at runtime. We'd have to do a bit of string processing and concat the TurboModule class name with the struct type. The solution would be simpler because it'd only modify the objective C and it wouldn't touch the Codegen system. **Edit:** I implemented it here: D14513078. The one downside of this design is that the name of the conversion function is individually constructed in two different locations in the code (i.e: no source of truth for this name). The other downside is that we have to rely on `RCTBridgeModuleNameForClass`, which we want to eliminate. This also computationally more expensive since it requires string processing/regex parsing and additional reflection. Therefore, we decided to move on with the current solution.

Summary:
If the `HasNewLayout` flag is `false`, we should not copy the data from YGStyle/YGLayout to ShadowNode because the node can be already sealed and because it's unnecessary. Previously we workaround this case with a special check in `setLayoutMetrics` method, but that can be unreliable because of some side-effects related to pixel rounding and comparing floats.
The new approach is much more robust and explicit.

Summary:
As a comment above changed lines states, RootShadowNode is a special one because it layouts itself. In normal case some parent node layouts its children, and it also checks getHasNewLayout flag. So, in the case of RootShadowNode it has to check its own flag by itself.
That fix should save some resources and generally correct.
After the change, changing a state of some node does not cause relayout process. If dirtying is required, the component should call `dirtyLayout()` explicitly in the constructor or in `adopt` method.

Summary:
After the change, YogaLayoutableShadowNode will preserve dirty flag (being false) in cases where:
* a node was cloned with same children;
* changes in props don't affect layout.
Motivation:
In Fabric we always were aggressive about dirting yoga nodes: when we clone the node, we always dirty underlying Yoga node. I think that was the case because we don't deeply understand how the system works and we always had more severe problems to fix. Now, we faced an issue that forces us to think about that problem carefully (more about that later).
(I don't expect that will improve TTI performance, but that's possible if we do a lot of changes in the hierarchy during initial load process.)
I see two main use cases where we have to be smart about dirtied yoga nodes:
Case 1. Native local commits which do *not* modify yoga styles.E.g. in a case where ScrollView updates the internal state (which has offset info) really really frequently. (It will be implemented later.) That `contentOffset` info does not or might not affect layout, so we should not pay for this.
Case 2. Legit React commits which do *not* modify yoga styles. E.g. in a case where only the background color of some view changes, we don't need to relayout anything. Unfortunately, we do this in Fabric because of two major reasons:
* We don't make a difference between any changes in Props.
* React constructs new children of cloned node iteratively, calling `appendChild`. That makes implementing optimization really challenging because we don't know when the process ends. And when it ends we have very few pieces of information about how the state looked before.
This diff stack will handle the problems of the first kind. The main motivation is: we want to have state updates to be as lean as possible.

Summary:
This is the couple of hacks I used after I finished #23802 in order to get fabric working on RNTester. This is inspired from prior work by kmagiera.
The goal of this PR is to show others what I’m struggling with, and to eventually merge it sans hacks.
- Yarn Install
- Uncomment the commented out pods in RNTester's pod file
- Open RNTesterPods workspace
- Run App
- this is only for pods, the non-pod RNTester will no longer work until updated with fabric too.
- `SurfaceHostingView` & `SurfaceHostingProxyRootView` both try to start the surface immediately, this leads to a race condition due to the javascript not having loaded yet, the hack here is:
1. Swizzle the `start` method on `RCTFabricSurface` to no-op when called.
2. Add observer for `RCTJavaScriptDidLoadNotification`
3. Call private method `_startAllSurfaces` on `_surfacePresenter` in AppDelegate when we receive `RCTJavaScriptDidLoadNotification`.

Summary:
Accidentally I noticed that the signature of Folly's hash_combine is different from boost's one.
The Folly's one is:
`size_t hash_combine(const T& t, const Ts&... ts)`, so the first argument is immutable and the method returns the result normally.
It means that all hashes that we compute in Fabric using `hash_combine` were `0`.
So I fixed it.
I have no idea why this difference exists, but some modern papers suggest that folly's variant has good chances to be standardized.
E.g.: http://open-std.org/JTC1/SC22/WG21/docs/papers/2017/p0814r0.pdf
Technically, it should improve performance, but I doubt that it can be more than 1-2 ms per screen TTI.

Having assignment operators for `YGNode` means that existing children on the node assigned to would have to be handled somehow.
Deallocating might be incorrect. Ignoring might leak.
Here, we `delete` copy assignment, and make move assignment private (it is used in `YGNode::reset()`).
Copy and move constructors *can* be implemented. The move constructor has to take ownership of the children, while the copy constructor leaves ownership untouched. Since children are copied lazily during layout, this does not expose true value semantics. We should consider removing the copy constructor, too.

Summary:
In React Native there are several use cases where React State is not the only input that affects the component tree. E.g., in case of a <Modal> component, the screen size directly affects the layout of components inside modal; in the case of uncontrolled <TextInput> component, the text inside the input affects the layout of the surrounding components. `State` is a special (legit!) workaround for all those similar cases. Native part of React Native maintains a special shared object between all nodes of the same family and use that during cloning and commits.
See coming commits to know how to use that.
In the near future State will fully replace LocalData concept but for simplicity they both exist for now.

Summary:
This PR implements the first part of [RFC0004: CocoaPods Support Improvements](353d44f649/proposals/0004-cocoapods-support-improvements.md), splitting the `React.podspec` into separate podspecs to more closely match the structure of Xcode projects.
The new structure aims to have one to one mapping between Xcode projects and podspecs. The only places where we differ from this mapping are:
* `React/React-DevSupport.podspec`: `DevSupport` is a part of `React.xcodeproj`, which corresponds to the `React-Core` pod. However, we can't include it in the `React-Core` pod because `DevSupport` depends on `React-RCTWebSocket`, which depends on `React-Core`. Pods may not have circular dependencies.
* The new pods under `ReactCommon/` don't have a corresponding `xcodeproj` because there are no `xcodproj` files in `ReactCommon/`. Those C++ modules are included in `React.xcodeproj`.
*Next steps (not in scope of this PR):*
- Start submitting the Podspecs to CocoaPods on a deploy (or turn the React Native repo into a spec repo): this is important in order to make the experience nicer for library consumers, so that it's not necessary to specify the local path of each Podspec in `Podfile`, you can just add `pod 'React', <version>`.
- Add `Podfile` to the default project template (I have a PR ready for this, but because of bugs related to subspecs, it's blocked on this PR)

Summary:
@public
Limit child cloning to layout calculation. This also allows for mixing shared and owned children.
Rationale:
We do allow for shared children if the caller manages themselves. The single known use case is React Native.
So far, we have cloned children eagerly whenever child lists are mutated, or layout is run. This was to allow for a quick check of the owner of any first child, assuming that either *all* or *no* child of a node are shared.
For Yoga/Java, we want to get rid of global weak JNI refs, and these are also used to invoke clone callbacks. We can achieve that goal by switching to an alternative approach, passing additional data to the layout pass. This additional data has to be passed to any configured cloning callback. Therefore, it is desirable to **only call cloning functions during the layout pass.**
The obvious solution seems to be to not uphold the invariant of the first child determining shared/owned state of all siblings, and allow for a mix of shared and own children.

Summary:
`SharedFunction` implements a pattern of a shared callable object that contains the same executable inside. It's similar to `std::function` with one important difference: when the object is copied, the stored function (and captured values) are shared between instances (not copied).
`SharedFunction` can be stored inside `std::function` because it's callable.
It useful in some scenarios, such as:
* When captured by `std::function` arguments are not copyable;
* When we need to replace the content of the callable later on the go.
We will use it in the coming diffs.

Summary:
Sometimes, when we deal with ImageRequest and ImageResponseObserverCoordinator we subscribe for status (or access the coordinator) without owning an ImageRequest. In those cases, we have to retain the coordinator explicitly.
For those cases, ImageRequest now exposes `ImageResponseObserverCoordinator` as a `std::shared_ptr`.
Eg, concretely in the code, `completionBlock` and `progressBlock` copied a raw pointer to the observer inside which can lead to a crash when ImageRequest is being deallocated before we received an image data.

Summary:
Our long-term plan is to completely illuminate `jsi::Value`-to-`folly::dynamic` serialization step in prop parsing process improving performance and memory pressure. At the same time, we don't want to introduce a hard dependency in application code to JSI because it exposes direct access to VM and prevents parsing some data that come *NOT* from JSVM.
RawValue is an extremely light-weight (hopefully fully optimized-out) abstraction that provides limited JSON-like and C++-idiomatic interface.
The current particular implementation is still using `folly::dynamic` inside, but I have fully JSI-powered one which will replace the current one right after we figure out how to deal with folly::dynamic-specific callsites. Or we can implement RawValue in a hybrid manner if a code-size implication of that will be minimal.

Summary:
This change is aiming to reduce some of the forking changes we have internally in order to use CxxReact for some additional out of tree platforms.
Some of the fixes allow more of the code to compile when using Microsoft Visual Studio Compiler. In particular the change around the default value of RN_EXPORT and some changes around how to enable the packing attribute.
Another change moves more of the code for JSBigFileString into the cpp file, so that people can share the header but replace the implementation as appropriate for other platforms.
And finally the removal of an unused header include.
This is unlikely to be the extent of the changes required for MSVC, but at least gets one of our complication blocks to work against an unforked RN.

- **UIManager_DispatchViewUpdates**: time right before RN moves the mount operations to the Queue that is going to be processed in the next tick UI thread
- **UIManager_BatchRunStart**: time right before the mountItems are going to be process in the UI Thread
- **UIManager_BatchedExecutionTime**: time it took to run batched mountItems (usually layout and prop updates on views)

Summary:
It's okay for TurboModules to not exist. Therefore, `__turboModuleProvider(moduleName)` should return null if `moduleName` doesn't refer to an actual TurboModule. The current implementation assumes that the TurboModule must exist, and therefore, it crashes the app when it doesn't (assertion error).
This change is important because it helps us land D13887962. When we switch `I18nResources` to `TurboModuleRegistry` in D13887962, on Wilde, it won't be found in `NativeModules`. Therefore, we'll try to lookup this module in `__turboModuleProvider`, and this will crash the app. It seems like `I18nResources` is a Java-only module?

Summary:
NativeModules are instantiated by the bridge. If they choose, they can capture the bridge instance that instantiated them. From within the NativeModule, the bridge can then be used to lookup other NativeModules. TurboModules have no way to do such a lookup.
Both NativeModules and TurboModules need to be able to query for one another. Therefore, we have four cases:
1. NativeModule accesses NativeModule.
2. NativeModule accesses TurboModule.
3. TurboModule accesses NativeModule.
4. TurboModule accesses TurboModule.
In summary, this solution extends the bridge to support querying TurboModules. It also introduces a `RCTTurboModuleLookupDelegate` protocol, which, implemented by `RCTTurboModuleManager`, supports querying TurboModules:
```
protocol RCTTurboModuleLookupDelegate <NSObject>
- (id)moduleForName:(NSString *)moduleName;
- (id)moduleForName:(NSString *)moduleName warnOnLookupFailure:(BOOL)warnOnLookupFailure;
- (BOOL)moduleIsInitialized:(NSString *)moduleName
end
```
If TurboModules want to query other TurboModules, then they need to implement this protocol and synthesize `turboModuleLookupDelegate`:
```
protocol RCTTurboModuleWithLookupCapabilities
property (nonatomic, weak) id<RCTTurboModuleLookupDelegate> turboModuleLookupDelegate;
end
```
NativeModules will continue to use `RCTBridge` to access other NativeModules. Nothing needs to change.
When we attach the bridge to `RCTTurboModuleManager`, we also attach `RCTTurboModuleManager` to the bridge as a `RCTTurboModuleLookupDelegate`. This allows the bridge to query TurboModules, which enables our NativeModules to transparently (i.e: without any NativeModule code modification) query TurboModules.
In an ideal world, all modules would be TurboModules. Until then, we're going to require that TurboModules use the bridge to query for NativeModules or TurboModules.
`RCTTurboModuleManager` keeps a map of all TurboModules that we instantiated. We simply search in this map and return the TurboModule.
This setup allows us to switch NativeModules to TurboModules without compromising their ability to use the bridge to search for other NativeModules (and TurboModules). When we write new TurboModules, we can have them use `RCTTurboModuleLookupDelegate` to do access other TurboModules. Eventually, after we migrate all NativeModules to TurboModules, we can migrate all old callsites to use `RCTTurboModuleLookupDelegate`.

Summary:
For better modularity, each module conforming to RCTTurboModule should provide a getter for the specific TurboModule instance for itself. This is a bit more extra work for devs, but simplify tooling and allow better modularity vs having a central function that provides the correct instance based on name.
Note: Android may or may not follow this new pattern -- TBD.

Summary:
I read my code and one thing stroke me: What if the same event emitter dispatches several events during the same event beat? In the previous implementation, only the first one will be delivered because the first `release` call consumes stored strong reference.
So, I changed the API a bit to make this more explicit: we have `retain` & `release` methods and we have a getter that works (multiple times) only if the object was successfully retained.

Summary: This diff implements a new algorithm that effectively marks `EventEmitter`s enabled or disabled. The previous implementation relied on a list of mutation instructions whereas the new one analyzes the shadow trees. The mutations-based approach didn't work well because mutations describe `ShadowView`s whereas some `ShadowNode`s are simply not views (like VirtualText), but we have to enable/disable them anyway.

Summary:
For some time we have had a nit trick inside `EventEmitter`: When event emitter is disabled, we switch to store `EventTarget` as a weak pointer instead of complete deleting it. Given some unpredictability of JS GC, it gave us some time to restore the pointer in case if we increment the counter right after decrementing this. Apparently, we found that it doesn't always work (obviously, sigh...), so we implement the `enableCounter_` and left this feature as it is assuming that it can nice optimization that illuminates some unnecessary constraints.
But, apparently, it's actually harmful, assuming that `jsi::WeakObject` (that thing that we use to refer to actual JS target) actually has "unsafe unretained" (not "weak") semantic.
So, we have to remove this.
This change will be particularly important for coming diffs in the stack.

Instead of the whole family of commit* and complete* methods, now we have one single `commit` method which performs pre- and post-commit operations and swap pointers in a thread-safe manner. The `commit` operation is also exposing `revision` number and allows perform multiple commit attempts.
`completeByReplacingShadowNode`, `measure` and `constraintLayout` are also going away to RootShadowNode class in the next commits.
Why?
* Nicer API;
* No more recursive_mutex, no more problems with thread jumps;
* All mutex locks are now leaf-locks, so no more deadlocks possible;
* Exposing `revision` should help with debugging races.

Summary:
After this diff D13403925 that got rid of `-ffast-math` we started to have a very odd behavior on Yoga when using release builds.
After digging a while we found that certain set of conditions on O2 and O3 optimization levels was causing Origami to set some `INFINITE` values on Yoga.
We found the root of the problem and fix it on Origami side. But I'm wondering if guarding agains `INFINITE` on Yoga side would be good too. Since now Yoga it's not using `-ffast-math` anymore, and I think infinite is not a a valid value anywhere on Yoga side, it seems to support the reason to guard against it.
I'm happy to abandon this diff if you guys think this is not a good solution.
