Summary:
This adds support for `adjustsFontSizeToFit` and `minimumFontScale` on Android. The implementation tries to match closely the behaviour on iOS (hardcoded 4px min size for example). It uses a simpler linear algorithm for now, opened to improving it now if it is a deal breaker or in a follow up.
See https://twitter.com/janicduplessis/status/1171147709979516929 for a more detailed thread about the implementation
## Changelog
[Android] [Added] - Implement `adjustsFontSizeToFit` on Android
Pull Request resolved: https://github.com/facebook/react-native/pull/26389
Test Plan: Tested by adding the existing `adjustsFontSizeToFit` example from the iOS text page to android. Also added a case for limiting size by using `maxHeight` instead of `numberOfLines`.

Summary:
In bridgeless mode, we use BridgelessReactContext, which overrides some methods on ReactApplicationContext like `getJSIModule` and returns true for `isBridgeless`. This is needed for things like getting the EventDispatcher, which is currently accessed from the UIManagerModule (which doesn't exist in bridgeless mode).
However, when we create Views in React Native we don't use the ReactApplicationContext directly; instead, we create a ThemedReactContext, which holds a reference to the RAC. It also initializes itself with the RAC's CatalystInstance, so that when you call methods on the TRC it can access native modules, etc.
This doesn't work in bridgeless mode, because the methods are overridden on the RAC, *not* the TRC. So in order for this work as expected, we need to delegate these methods to the RAC member variable. In this diff I'm just doing this for `isBridgeless` and `getJSIModule` so that accessing the EventDispatcher works.

This bug was caused by D18196901, when we changed the base class of ReactEditText from EditText to AppCompatEditText.

Summary:
Because the `mCatalystInstance` of the ReactContext can be null during teardown, there are technicaly cases where `UIManagerHelper.getUIManager` can return null. In those cases we check for a CatalystInstance and raise a SoftException, and return null. We must then guard in every case where we call `getUIManager` to prevent NullPointerExceptions.
See T56103679.
Currently crashes are coming from `PropsAnimatedNode.restoreDefaultValues` calling `UIManagerModule.synchronouslyUpdateViewOnUIThread` on teardown/at the end of an animation as RN is being torn down.
This can happen in both Paper and Fabric.
In dev this will still crash because the SoftException will trigger a crash. It will be a noop with logged warnings in production builds.

Summary:
This PR addresses issue https://github.com/facebook/react-native/issues/23870 (`View.getGlobalVisibleRect()` is broken in some use cases)
The issue affects the following Android APIs:
- ViewGroup.getChildVisibleRect()
- View.getGlobalVisibleRect() (Which calls into ViewGroup.getChildVisibleRect)
- View.getLocalVisibleRect() (Which calls into View.getGlobalVisibleRect())
According to Android documentation, View.getGlobalVisibleRect() should provide a rect for a given view that has been clipped by the bounds of all of its parent views up the view hierarchy. It does so through the use of the recursive function ViewGroup.getChildVisibleRect().
Since React Native has a separate clipping mechanism that does not rely on Android UI's clipping implementation, ViewGroup.getChildVisibleRect() is unable to determine that a rect should be clipped if the clipping view is a ReactClippingViewGroup. This resultantly breaks some important use cases for things like testing with Detox, which relies on this functionality to tell when a component is on-screen, as explained in the above referenced issue.
The rationale of the fix is essentially to implement logic analogous to [ViewGroup.getChildVisibleRect()](https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/view/ViewGroup.java#6176), discarding irrelevant Android clipping modes, and instead testing against the 'overflow' property, restoring the originally intended functionality. This is implemented as an override to ViewGroup.getChildVisibleRect() in the following classes:
- ReactViewGroup
- ReactScrollView
- ReactHorizontalScrollView
Unfortunately, since the public ViewGroup.getChildVisibleRect() API recurses into a `hide` annotated API which cannot be overridden, it was necessary to provide this override in each of the above React Native classes to ensure the superclass implementation would not be called, which would break the recursion.
## Changelog
[Android] [Fixed] - View.getGlobalVisibleRect() clips result rect properly when overflow is 'hidden'
Pull Request resolved: https://github.com/facebook/react-native/pull/26334
Test Plan:
The functionality in question is neither used internally nor exposed by React Native, and thus only affects Android native modules that use the above referenced APIs.
As such, I have primarily performed testing with a forked example project that had been submitted with issue https://github.com/facebook/react-native/issues/23870, originally by d4vidi.
The example project can be found here:
- [Configured to build against RN Master](https://github.com/davidbiedenbach/RNClipVisibilityBugDemo/tree/rn-master)
- [Configured to build against PR branch](https://github.com/davidbiedenbach/RNClipVisibilityBugDemo/tree/fix-23870)

### Bug in effect:
When built against RN master, it can be observed that fully clipped views are reported as visible, as in the below screenshots.
#### Views inside a ReactViewGroup do not report as clipped
#### Views inside a ReactScrollView do not report as clipped
#### Views inside a ReactHorizontalScrollView do not report clipping properly
### Bug fixed

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:
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:
React Native components need a mechanism to specify their value to assistive technologies. This PR adds the notion of accessibilityValueDescription-- a property which either contains a textual description of a component's value, or for range-based components, such as sliders and progress bars, it contains range information (minimum, current, and maximum).
On iOS, the range-based info if present is converted into a percentage and added to the accessibilityValue property of the UIView. If text is present as part of the accessibilityValueDescription, it is used instead of the range-based information.
On Android, any range-based information in accessibilityValueDescription is exposed in the AccessibilityNodeInfo's RangeInfo. Text which is part of accessibilityValueDescription is appended to the content description.

Summary:
Our JS codegen assumes that all Android view managers extend `BaseViewManager` which allows generated delegates to set base view props using `BaseViewManagerDelegate`, see and example of the generated delegate for `FbReactTTRCStepRenderFlagManager`:
```
public class TTRCStepRenderFlagManagerDelegate<T extends View, U extends BaseViewManager<T, ? extends LayoutShadowNode> & TTRCStepRenderFlagManagerInterface<T>>{
public TTRCStepRenderFlagManagerDelegate(U viewManager) {
super(viewManager);
}
Override
public void setProperty(T view, String propName, Nullable Object value) {
switch (propName) {
case "traceId":
mViewManager.setTraceId(view, value == null ? null : (String) value);
break;
case "stepName":
mViewManager.setStepName(view, value == null ? null : (String) value);
break;
default:
super.setProperty(view, propName, value);
}
}
}
```
The problem is that `FbReactTTRCStepRenderFlagManager` doesn't extend `BaseViewManager`, but `ViewManager`, which means that we cannot use it with the generated delegate. We cannot use `ViewManager` instead of `BaseViewManager` in our JS codegen either, otherwise we will not be able to set base view props.
This diff makes it possible for delegates generated by JS to be used by Android view managers that do not extend `BaseViewManager`. By having a `BaseViewManagerInterface` we will be able to introduce a no-op base view manager implementation and wrap our original view manager in it so that we can pass as a constructor parameter to `BaseViewManagerDelegate`.
See an example of this approach for `FbReactTTRCStepRenderFlagManager`:
```
public class FbReactTTRCStepRenderFlagManager extends ViewManager<FbReactTTRCStepRenderFlag, ReactShadowNodeImpl> implements TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> {
private final ViewManagerDelegate<FbReactTTRCStepRenderFlag> mDelegate;
public FbReactTTRCStepRenderFlagManager() {
mDelegate = new TTRCStepRenderFlagManagerDelegate<>(new ViewManagerWrapper(this));
}
...
private static class ViewManagerWrapper extends BaseViewManagerAdapter<FbReactTTRCStepRenderFlag> implements TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> {
private final TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> mViewManager;
private FbReactTTRCStepRenderFlagManagerAdapter(TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> viewManager) {
mViewManager = viewManager;

mViewManager.setTraceId(view, traceId);
}
Override
public void setStepName(FbReactTTRCStepRenderFlag view, Nullable String stepName) {
mViewManager.setStepName(view, stepName);
