Summary:
See https://github.com/facebook/react-native/issues/10845
onSizeChanged is enqueueing a runnable from the ui thread that references a shadow view by id on the native modules thread. Since the shadow thread 'runs ahead' of the UI thread (e.g. it has a newer state of the world than the UI thread), this isn't safe. By the time that code block runs, it's possible that an update from JS has already removed that view from the shadow hierarchy (a change which would then propagate to the native hierarchy on the UI thread).

Summary:
I don't remember exactly where we talked about this but LayoutAnimation on Android is pretty stable now so there's no reason to keep it behind an experimental flag anymore. The only part that is not really stable is delete animations, so what I did is remove the default delete animation that we provide in presets.
**Test plan**
Tested that layout animations work properly without any config.

Summary:
This diff adds display:none support to React Native. This enables hiding components which still calling their render method and keeping them within the state of your application. This enables preserving state in a component even though the component is not visible. Previously this was often implemented by rendering a component off screen as a work around. See below playground for usage.
```
class Playground extends React.Component {
render() {
return (
<View style={{width: '100%', height: '100%', flexDirection: 'row', backgroundColor: 'white'}}>
<View style={{width: 100, height: 100, display: 'none', backgroundColor: 'red'}}/>
<View style={{width: 100, height: 100, backgroundColor: 'blue'}}/>
</View>
);
}

Summary:
Android API 15 still have 1.5~2.0% distribution (refer: [Dashboard - Android Developer](https://developer.android.com/ndk/guides/standalone_toolchain.html#creating_the_toolchain)).
React Native is a good tec but many companies cannot endure loose their consumer. [Choreographer](https://developer.android.com/reference/android/view/Choreographer.html) triggered UI operation is the only reason that React Native Android sdk use minSdkVersion 16, so we can use a backward solution **only in API 15**: [Handler](https://developer.android.com/reference/android/os/Handler.html).
In this PR, the biggest change is :
- Make core operation of ReactChoreographer to an interface: ReactUIDriver;
- Impl ReactUIDriver by Handler => UIDriverHandlerImpl, refactor ReactChoreographer to UIDriverChoreographerImpl;
- Let UIDriverFactory to choose which one impl would be in use. (Only use handler in api 15).

Summary:
The PR description has been updated to reflect the new approach.
**Breaking Change Summary**
On Android, the following properties now return a different number:
- `Dimensions.get('window').fontScale`
- `Dimensions.get('screen').fontScale`
- `PixelRatio.getFontScale()`
This is a breaking change to anyone who was using these properties because the meaning of these properties has now changed.
These properties used to return a value representing font scale times density ([`DisplayMetrics.scaledDensity`](https://developer.android.com/reference/android/util/DisplayMetrics.html#scaledDensity)). Now they return a value representing just font scale ([`Configuration.fontScale`](https://developer.android.com/reference/android/content/res/Configuration.html#fontScale)).
**PR Description**
This PR changes a few things:
- Correctly exposes the font scale to JavaScript as `Dimensions.get('screen').fontScale`. UIManager was exporting `DisplayMetrics.scaledDensity` under the name `fontScale`. How

Summary:
If we throw an exception from a UIOperation, the UI is likely in a bad state and we shouldn't execute any other operations on it. In non-dev mode, this would mean we've crashed and don't have to worry about that. But in dev mode, we may have shown a redbox and the instance is still active. This means doing something like reloading, which will trigger onPause and thus flush more UI operations, can crash the app while its sitting on a red box.
This diff aims to prevent that by no longer executing UI operations after one has thrown an exception.

Summary:
Android has a text API called breakStrategy for controlling how paragraphs are broken up into lines. For example, some modes support automatically hyphenating words so a word can be split across lines while others do not.
One source of complexity is that Android provides different defaults for `breakStrategy` for `TextView` vs `EditText`. `TextView`'s default is `BREAK_STRATEGY_HIGH_QUALITY` while `EditText`'s default is `BREAK_STRATEGY_SIMPLE`.
In addition to exposing `textBreakStrategy`, this change also fixes a couple of rendering glitches with `Text` and `TextInput`. `TextView` and `EditText` have different default values for `breakStrategy` and `hyphenationFrequency` than `StaticLayout`. Consequently, we were using different parameters for measuring and rendering. Whenever measuring and rendering parameters are inconsistent, it can result in visual glitches such as the text taking up too much space or being clipped.
This change fixes these inconsistencies by setting `breakStrategy` and `hyphenat

Summary:
This PR fixes#11096.
I don't know enough the ReactAndroid's source code so I don't know if this is correct but I hope it is.
In a recent commit (https://github.com/facebook/react-native/commit/d4b8ae7a8a3de314b5813e0bfcdf5fb265129d43), the `dispatchUpdates` method now returns a boolean to dispatch or not the `onLayout` event. This works well but if the content is unchanged, the line `nativeViewHierarchyOptimizer.handleUpdateLayout(this);` is never called. I don't know if it was intended but it was this which introduces my issue. I called this again even if the content didn't change. This was the behaviour before 0.38 so I guess I didn't break anything.
**Test plan (required)**
I tested my pretty big app with this fix and every screen is ok.

Summary:
When using text inputs inside a ScrollView with `keyboardShouldPersistTaps=false` (default behavior) tapping another text input dismisses the keyboard instead of keeping it open and focusing the new text input which I think is the better and expected behavior.
See #10628 for more discussion about that. Note that this affects nothing but the behavior with text inputs unlike #10628.
