Summary:
We are seeing these errors in prod:
```
TypeError: Cannot read property '_nativeTag' of null
at
ReactNativeFiberHostComponent.prototype.measureLayout(ReactNativeRenderer-prod.fb.js:1594)
ScrollResponderMixin.scrollResponderScrollNativeHandleToKeyboard(ScrollResponder.js:557)
```
This error is coming from these lines: https://github.com/facebook/react-native/blob/69c38e5a639f34620038ae5724426c92c355e509/Libraries/Components/ScrollResponder.js#L563-L567
Either `nodeHandle` is null or `this.getInnerViewRef()`. If `nodeHandle` was null, we'd get an error that we can't call `measureLayout` on null. So `this.getInnerViewRef()` must be null.
In the React Native Renderer this error of `_nativeTag of null` is coming from this line: https://github.com/facebook/react/blob/db8afe4f6318dba422177a2054204ef089570ad8/packages/react-native-renderer/src/ReactNativeFiberHostComponent.js#L84
Which means indeed `this.getInnerViewRef()` is null.
So adding a null check here which is what we do at all the other product callsites of `measureLayout`. Flow should have caught this, but because ScrollView is one of the only components left using mixins (ScrollResponder), `this.getInnerViewRef` is typed as `any` instead of what it should be:
```
?React.ElementRef<Class<ReactNative.NativeComponent<mixed>>>
```
If `scrollResponder` was typed correctly then Flow would have caught this.

Summary:
When converting an array into a Vec, we should also check whether the array pointer is `kCFNull`.
In TurboModules, when an object's property is mapped to null, we simply do not insert that property into the corresponding `NSDictionary`. This causes the `NSDictionary` lookup to return `nil`. In the legacy infra, it looks like we may insert `kCFNull` into the `NSDictionary`, which will cause the lookup to return `kCFNull`.

Summary: This diff fixes the issue with view paddings in Fabric introduced in D17081799. In Paper setting padding on a view was only supported for Text and TextInput components (see https://fburl.com/codesearch/6r6lu5vd). We want to keep Fabric backwards compatible, so we delegate setting the padding to the view manager instead of setting it directly on the view. In this way we can have a no-op implementation in the base view manager and implement this method only in view managers that support setting padding (ReactTextInputManager and ReactTextViewManager at the moment).

Summary:
Some NativeModules belong to their own buck target (separate from `ReactInternal`). We shouldn't move those NativeModules to `CoreModuels`, because that would unnecessarily bloat `CoreModules`.
In this diff, I extended the `update-plugins.js` script to also generate plugin stubs for those additional targets. This way, we can convert those NativeModules to TurboModules without moving them to CoreModules.
Now, in `update-plugins.js`, we have this array:
```
const libraries = [
{
name: 'CoreModules',
outputFiles: {
ios: ['CoreModulesPlugins.h', 'CoreModulesPlugins.mm'],
android: [],
},
outputPath: {
ios: `${GITHUB_DIR}/React/CoreModules`,
android: '',
},
},
];
```
To codegen another pair of plugin files for another target, simply insert to this array.
**Note:** We'll have to modify RNTesterTurboModuleProvider, but I can take care of that when I setup RNTester for TurboModules.

Summary:
Because of the changes made in Fabric, the order of the execution of some methods in ViewManager has changed. In Paper the following order was guaranteed: `createViewInstance -> addEventEmitters -> updateProperties -> onAfterUpdateTransaction`. But in Fabric, the order is the following: `createViewInstance -> updateProperties -> onAfterUpdateTransaction -> addEventEmitters`. This change can actually break some existing view managers, because they rely on the fact that `addEventEmitters` will be called before `onAfterUpdateTransaction`. Check ReactVideoManager:
```
ReactModule(name = ReactVideoManager.REACT_CLASS)
public class ReactVideoManager extends SimpleViewManager<ReactVideoPlayer>
implements VideoManagerInterface<ReactVideoPlayer> {
...
Override
protected void onAfterUpdateTransaction(ReactVideoPlayer view) {
super.onAfterUpdateTransaction(view);
view.commitChanges();
}
Override
protected void addEventEmitters(
final ThemedReactContext reactContext, final ReactVideoPlayer view) {
view.setStateChangedListener(
new ReactVideoPlayer.PlayerStateChangedListener() {
...
}
```
As you can see there is a state change listener registered in `addEventEmitters` and `view.commitChanges()` can actually cause a state change. It means that if `onAfterUpdateTransaction` is executed before `addEventEmitters`, the state change listener will be added after a state change has happened and the event will be missed.

Summary:
When sliders are adjusted via accessibility, no onSlidingComplete callback is
generated. This causes problems for components which perform behavior in this
callback, and means that such components don't behave properly when adjusted via
accessibility. For example, if an app hosting a volume control slider only commits the volume change to the hardware on onSlidingComplete, it is impossible for a screen reader user to ever actually adjust the volume.
Ensure that sliders call the onSlidingComplete callback after adjusted via
accessibility.

Summary:
`ReactRootView.startReactApplication` takes a `Bundle` argument called `initialProperties`. This is translated to a `ReadableMap` via `Arguments.fromBundle`. If the bundle contains an array of bundles, this gets translated by `Arguments.fromArray`.
If the bundle was passed from one activity to another via intent extras, however, there is a problem. After the bundle has been marshaled and unmarshaled, the array of `Bundle`s come out the other end as an arrap of `Parcelable`s, although each array element remains a `Bundle`. This results in an "Unknown array type" exception.
This PR fixes this by adding support for `Parcelable` arrays – provided they contain only members of type `Bundle`.

Summary:
In `CatalystInstanceImpl.destroy()`, we require the TurboModuleManager using the [following lines](https://fburl.com/diffusion/a4y6wbft):
```
final JSIModule turboModuleManager =
ReactFeatureFlags.useTurboModules
? mJSIModuleRegistry.getModule(JSIModuleType.TurboModuleManager)
: null;
```
For some strange reason, even though `ReactFeatureFlags.useTurboModules` is true, the TurboModuleManager isn't registered with mJSIModuleRegistry. I spent some time looking through the code, but I couldn't figure out why. These lines actually aren't necessary, so it's possible to fix the issue by simply working around it, which is what this diff does. We shouldn't have been double requiring the TurboModuleManager anyways, since `CatalystInstance.java` has a method to set the TurboModuleManager, which we call in `ReactInstanceManager.createReactContext`.
## Alternative approach
I could push this diff to the next cut, and instead land a diff that adds debug information to the native crash. At the cost of a week, it may help us figure out why we're seeing the crash. Thoughts? cc fkgozali
