Assistive technologies use the accessibility role of a component to tell the disabled user what the component is, and provide hints about how to use it. Many important roles do not have analog AccessibilityTraits on iOS. This PR adds many critical roles, such as editabletext, checkbox, menu, and switch to name a few.
Accessibility states are used to convey the current state of a component. This PR adds several critical states such as checked, unchecked, on and off.

Summary: For some reason the scroll events are sometimes generated with highly irregular spacing, some coming less than a millisecond apart. For interactions that must track scrolling exactly, this can cause them to glitch. With a scroll throttle of less than 17 ms, the intention is clear that the UI should be updated in sync with the scroll view so we shouldn't drop any events.

Summary:
@public
In order to encapsulate property access on `YGStyle`, as a first measure we wrap all fields with accessors.
This will e.g. enable dynamic property storage and instrumentation in the future.
All accessors have a `const` version that allows direct access via `const&`. For mutation, bit fields are wrapped with a custom reference object.
This style allows for the least amount of changes in client code. Property access simply needs appended parens, eg `style.direction` becomes `style.direction`.

Summary:
ShadowTree commits happen concurrently with limited synchronization that only ensures the correctness of the commit from ShadowTree perspective.
At the same time artifacts of the commit () needs to be delivered (also concurrently) to the proper thread and executed in order (not-concurrently). To achieve this we need some synchronization mechanism on the receiving (mounting) side. This class implements this process.
Practically, this diff fixes a problem with glitching UI during the very first render of Fabric screen.

Summary:
Registries, providers, providers of registries, registres of providers. All that can be really confusing, but that represents best the constraints and desires that we have:
* We need to be able to register components on-the-fly (so we need a mechanism that will propagate changes);
* We don't want to register ComponentDescriptors separately from ComponentView classes;
* C++ not always gives us abstractions that we want (e.g. pointers to constructors).
After the change, we can remove the whole Buck target that has a bunch of handwritten boilerplate code.
There is a still room for polish and removing some concepts, types or classes but this diff is already huge.

ComponentDescriptorProvider represents unified way to create a particular descriptor.
Now all ComponentViews (which support RCTComponentViewProtocol) expose a `ComponentDescriptorProvider` which will allow creating and registering ComponentDescriptor instances for all visual components automatically as a part of ComponentView registration process.
Don't panic, everything is still being as explicit as it always was, no magic involved; we just will have only one registration step instead of two parallel.
That also opens a way to register components on the fly.

Summary:
Would like feedback from the community as this may not be the best solution for all
I would like to restrict (or paginate) the fling of a horizontal ScrollView when `snapToInterval` is set. This is not currently possible with `pagingEnabled`, since the pagination works only when items are the entire width of the ScrollView.
This implementation simply restricts the predicted `targetOffset` found from the `x` velocity and replaces it with the offset when the pan gesture ended.
To get pagination working, I may paginate based on the interval by calculating the offset delta from the beginning of the gesture to current offset and restricting the scrolling behavior to the `snapToInterval`. If this is preferred, I can update this PR or make a new one, but wanted to start a discussion since it seems like there are many in the community that would like this feature #21302 .

Summary:
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.

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:
In the case where the first rootView we load enables Fabric, the UIManagerBinding ended up calling AppRegistry (JS) too early, before the bridge was fully ready. This means AppRegistry wasn't set up yet, causing redbox.
To fix this, RuntimeExecutor impl should ask the bridge to queue the callback instead of asking the MessageQueueThread directly. MessageQueueThread only works well IFF the bridge is alive, but it has no knowledge about whether the bridge is alive or not. To support this, we add `invokeAsync` impl to the RCTCxxBridge.

The root cause comes down to the fact that historically `-DFOO=0` and `-DFOO=1` patterns have been used when it comes to preprocessor definitions and various engineers use `#ifdef FOO` and `#if FOO` interchangeably. That results in an incorrect pattern because the real evaluation is following:
- `FOO` not defined: `#if FOO` = `FALSE`, `#ifdef FOO` = `FALSE`.
- `-DFOO=0`: `#if FOO` = `FALSE`, `#ifdef FOO` = `TRUE`.
- `-DFOO=1`: `#if FOO` = `TRUE`, `#ifdef FOO` = `TRUE`.

Summary:
Main change is to the property diffing - we now use the last known props set on the view rather than the default props to compute the diff. This requires exposing a `getProps` method on all view components which should be fine I think.
I also realized that in more complex animations with multiple nodes, the node that the animation starts on might not be connected to a view, so we don't know if it's fabric just based on that, so we have to do a recursive search through the children to find if there are any that are associated with a fabric view to decide we should start the animation immediately. Unfortunately there can still be a timing gap here since the animated API is async and the uimanager API is sync - I'll need to change the animated API to be sync to completely fix this.

Summary:
ScrollView's scrollTo behavior on iOS was recently changed to limit the offset to the content size plus any content inset (see #23427). This departure from the old behavior created UI issues for anyone that is using the over-scroll ability for the purpose of positioning elements at specific coordinates on the screen. Examples include using this behavior to position TextInputs above the virtual keyboard programmatically when focused or moving drop down elements positioned near the bottom of the content toward the top of the screen when selected to show a larger absolutely positioned item list. Default behavior does not change and this is an "opt-in" type of prop to re-enable the old behavior.

However, if the `contentInset` prop is set for the `FlatList`, I think `contentOffset` can be a negative value after refreshing and should be greater than `-contentInset.top`.
As I reported the bug in that issue, If I am using `contentInset` prop to the `FlatList`, making `contentOffset` value be always 0 when refreshing ends causes something wrong situation.

Summary:
Xcode 10.2 forbids creating categories for swift class that uses `+load` method. In react-native categories like this are used to register swift classes as modules (macro `RCT_EXTERN_MODULE`) This PR changes it to use `__attribute__((constructor))` instead of objc `+load` method.
I introduced new macro for this purpose, `RCT_EXPORT_MODULE_NO_LOAD`, it expands in something like:
```
void RCTRegisterModule(Class);
+ (NSString *)moduleName {
return @"jsNameFoo";
}
__attribute__((constructor)) static void initialize_ObjcClassFoo{
RCTRegisterModule([ObjcClassFoo class]);
}
```
Functions marked with `__attribute__((constructor))` are run before main and after all `+load` methods, so it seems like correct thing to do.
