Summary:
The RootView being managed by Fabric should have an id of View.NO_ID when it is "handed over" to RN. This is true for Fabric and non-Fabric
and setting a custom id on the ReactRootView has never been supported. I'm temporarily (?) adding an additional check earlier and into ReactRootView to hopefully
catch any of these issues early.

Summary:
There is a race between PreAllocateMountItems executing and killing off stale SurfaceMountingManagers.
For now I'm simplifying the "eviction" mechanism. We just keep up to 15 SurfaceMountingManagers around and start evicting them from the least-recently-referenced one.
Hopefully this logic can be simplified in the future.
I'm also sneaking in a small perf optimization for PreAllocateMountItem: don't queue them if the associated surface is already stopped, because chewing through a bunch of dead PreAllocateMountItems on the UI thread can be expensive.

Summary:
In some cases, onMeasure/onLayout are called on the RootView before `startSurface` in Fabric has been able to set surfaceId on the RootView.
With the new SurfaceMountingManager, this causes a crash because we need a valid surfaceId to perform an operation. Before the SurfaceMountingManager refactor, a surfaceId of 0 would be passed to `mBinding.setConstraints` in the FabricUIManager, and setConstraints in C++ noops if there's an invalid surfaceId.
For now, FabricUIManager will also fail silently if the surfaceId is invalid when updateRootLayoutSpecs is called, just to be conservative and to be consistent with previous behavior. This will be upgraded to a hard-crash in the future.

Summary:
Right now, running the codegen parser on regular JavaScript files causes it to throw an error:
https://www.internalfb.com/intern/diffusion/FBS/browsefile/master/xplat/js/react-native-github/packages/react-native-codegen/src/parsers/flow/index.js?commit=1e93f27aac8890f1731650fdcc38b702ae8874e2&lines=59-63%2C106-107
This makes the parser less usable, because you can't simply loop over a list of JavaScript files, and run codegen on them. You need to do some filtering beforehand, or surround each invocation of the parser with a try/catch.
Our codegen schema supports the idea of an empty schema:
```
{
modules: {}
}
```
To improve the parser's ergonomics, this diff migrates the codegen parser over to returning the empty schema when it cannot detect a Component or NativeModule spec inside a JavaScript file.

Summary:
Refactor EventEmitters to take an optional SurfaceId that Fabric will use, and non-Fabric will not.
Migrating touches is a good proof-of-concept for how this could be used generally, and as it turns out, TouchEvent's API is more flexible than most other event APIs (because it uses a dictionary to pass data around, so we can just stuff SurfaceId into it - not efficient, but flexible).
All new APIs are backwards-compatible and designed to work with old-style events, with Fabric and non-Fabric. Native Views that migrate to the new API will be backwards-compatible and get an efficiency boost in Fabric.

Summary:
There's a field called `surfaceID` in a couple of classes that isn't the same as the integer `surfaceId` in Fabric.
For consistency, I've deprecated a couple of them, or renamed when appropriate.
In addition, now we're passing the actual integer surfaceId into the ThemedReactContext. This means that every single View created in Fabric gets annotated with the surfaceId it's in. Currently this isn't used, but the idea is that now each View has a mapping back to its surface, which could be used to simplify / optimize operations with SurfaceMountingManager. In particular, we might be able to use this in the future to optimize animations and/or event emitters.

Summary:
This refactors MountingManager into a minimal API that shims into a more fully-featured SurfaceMountingManager. The SurfaceMountingManager keeps track of surface start/stop, surface ID, and surface Context.
This solves a number of issues around (1) race conditions around StopSurface/StartSurface, (2) memory management of Views, (3)
Concrete improvements:
1. Simpler to reason about race conditions around StopSurface/StartSurface.
2. 1:1 relationship between SurfaceId and all Views/tags.
3. When surface is stopped, all descendent Views can be GC'd immediately.
4. Fixed separation of concerns and leaky abstractions: surfaceId/rootTag and Surface Context are now stored and manipulated *only* in SurfaceMountingManager.
5. Simpler StopSurface flow: we simply remove references to all Views, and the Fragment (outside of the scope of this code) removes the RootView. This will trigger GC and we do ~0 work. Previously, we ran a REMOVE and DELETE instruction and kept track of each View in a HashMap. Now we can simply delete the map and move on.
The caveat: NativeAnimated (or other native modules that go through UIManager). APIs like `updateProps` currently uses only the ReactTag and does not store SurfaceId. This is a good argument for moving away from ReactTag, at least in its current incarnation, but: for now this requires that you do a lookup of a ReactTag across N surfaces (worst-case) to determine which Surface a ReactTag is in.
So, to summarize, the "con" of this approach is that now `getSurfaceManagerForViewEnforced` could be slower. It is used in:
* NativeAnimatedModule calls `updateProps` through UIManager
* FabricEventEmitter calls `receiveEvent` on FabricUIManager directly
* On audit, I could find zero native callsites to `sendAccessibilityEvent` through UIManager

Summary:
MountingManager keeps a map of tags to Views, and attempts to clean it up by (1) deleting tags when they're explicitly deleted, (2) recursively deleting all Views when the View hierarchy is torn down.
However, there appear to be.... substantial gaps here. In tests, when navigating between screen X -> screen Y -> back to X (triggering a StopSurface), each "StopSurface" resulted in 200-600 Views being leaked (!).
What is causing these leaks? Well, for one, the "dropView" mechanism isn't perfect, so it might be missed Views. Second, Views don't always guarantee that `reactTag == getId()`, so that could result in leaks. Third, View preallocation on Android complicates things: Views can be preallocated and then never even inserted into the View hierarchy, so DELETE mutations could never be issued. Fourth, StopSurface is also complicated on Android (largely because of View preallocatioAndroid (largely because of View preallocation).
So, I introduce a new mechanism: keep a list of all tags for a surface, and remove all tags for a surface when the surface is torn down. This should be fool-proof: it handles preallocation and normal creation; it can handle deletes; and we're guaranteed that tags cannot be added after a surface is stopped.
Is this overly complicating things? Well, hopefully we can simplify all of this in the longterm. But until we get rid of View Preallocation, it seems like we need this mechanism - and View Preallocation might be around for a while, or forever.
Other thoughts: it's possible that using other data-structures could be more efficient, but I'm guessing the perf implications here are marginal (compared to the insane amount of memory leaks we're fixing). It could also simplify things to have a SurfaceMountingManager interface that implies all actions happen on a specific surface, including teardown.

Additionally, this crash actually has nothing to do with (un)flattening or the differ; it is a side-effect of stale ShadowNodes being cloned, which I believe is either UB or a contract violation.

Summary:
This diff changes the type of the SwipeRefreshLayoutManager.size prop from Int to String in Fabric.
The current implementation of this prop allows JS developers to use "int" type when fabric is enables and "int or string" types when using Fabric is disabled.
Since long term we want to only support "string" type for this prop, I'm changing the type of the prop to be String.
After my diff Fabric will start supporting only "string" types, non fabric screens will keep supporting "int or string" values.
**Will this break production?**
No, because there are no usages of RefreshControl.Size prop in fbsource
**What about if someone start using this prop next week?**
IMO It's very unlikely because of the nature of this prop, I will be monitoring next week and if there's an usage it will be detected by flow when trying to land D25933457.
