This race condition only shows itself with flag `useOptimizedEventBatchingOnAndroid`
# Problem
EventBeat assumes method `induce` will be called repeatedly on every UI tick. This is true for iOS and existing implementation of event beat on Android. The first early exist inside of `induce` method is built with this assumption.
`useOptimizedEventBatchingOnAndroid` on Android changes this. `induce` will only be called after FabricUIManager.onRequestEventBeat is invoked and then it will stop. For one `FabricUIManager.onRequestEventBeat` call, `EventBeat::induce` is called once. And there is a chance for race condition.
Here is a simplified implementation of `induce`. This method may be called many times in sequence. The caller will set [isRequested_](https://github.com/facebook/react-native/blob/main/packages/react-native/ReactCommon/react/renderer/core/EventBeat.cpp#L25) and then invoke [FabricUIManager.onRequestEventBeat](https://github.com/facebook/react-native/blob/main/packages/react-native/ReactAndroid/src/main/jni/react/fabric/AndroidEventBeat.cpp#L43). Notice how `FabricUIManager.onRequestEventBeat` is debounced if `isRequested_` flag is true.
```
void EventBeat::induce() const {
if (!isRequested_ || isBeatCallbackScheduled_) {
// isRequested_ is not set to false in case isBeatCallbackScheduled_) is true.
return;
}
isRequested_ = false;
isBeatCallbackScheduled_ = true;
auto beat = std::function<void(jsi::Runtime&)>(
// on JS queue
isBeatCallbackScheduled_ = false;
// beatCallback_(runtime)
}
runtimeScheduler_.scheduleWork(std::move(beat));
}
```
This can get into a state where `isRequested_` is not reset back to false even though `EventBeat::induce` is called when `isBeatCallbackScheduled_` is true.
`AndroidEventBeat::request` -> `isRequested_` is set to true -> `FabricUIManager::onRequestEventBeat` -> `EventBeat::induce` -> `isRequested_` is set to false -> `isBeatCallbackScheduled_` is set to true -> `AndroidEventBeat::request` -> `FabricUIManager::onRequestEventBeat` -> `EventBeat::induce` (early exit because `isBeatCallbackScheduled_` is true) -> `beat` is executed on the JS thread.
From this point on, subsequent calls to `AndroidEventBeat::request` are always debounced because flag `isRequested_` is true.
Any subsequent event on Android will end up calling `EventBeat::induce` and the mechanism gets unstuck.
# The fix
The fix is simple, any time `EventBeat::induce` is called, make sure `request_` flag is set to false. This then satisfied the expectation of `useOptimizedEventBatchingOnAndroid` optimisation.

In [#47176](https://github.com/facebook/react-native/pull/47176) we disabled the generation of the component registration for app specific components as it was creating a circular dependency between the app and React Native.
However, we made a couple of typos that make it not work as expected and users picked up those typos soon.
This change fixes them for good.

Pull Request resolved: https://github.com/facebook/react-native/pull/47278
When we have multiple spans of text inside a <Text> element, React will emit these as separate RawText ShadowNodes. RawText shadow nodes cannot have any properties beyond the text they contain, yet our current AttributedText logic will generate a separate span for each and duplicate all the relevant properties.
This can be particularly inefficient when JSX is used to interpolate strings, e.g. `<Text styles={styles.text}>Example {i}/{count}</Text>` results in 4 raw text elements with duplicated properties.

Enables the two following feature flags:
- `enableAnimatedAllowlist`
- `enableAnimatedPropsMemo`
The former enables the use of an experimental optimization to provide `unstable_createAnimatedComponentWithAllowlist` and `useAnimatedProps` an allowlist of props that reduces the set of props iterated over by to find props with `AnimatedNode` (e.g. `Animated.Value`) instance values.
The latter enables improved memoization logic in `Animated` so that its intenal state is invalidated less frequently, reducing the cost of updating `Animated` components.

I am trying to help someone with creating a sticky header on a scrollview, specifically one that floats on the side of the scrollview instead of the top Currently we can't really do that, since utilizing `position: absolute` to layout this properly will get overriden by the header styles changed in this diff
This was only added since static was the default and we needed to apply zIndex. With proper static implementation that is no longer the case, so I think it makes sense to remove this to support this use case.

That's a reland of D65540601
The `UIManager.eventDispatcher` return type is wrong and is causing a breaking change in 0.77
For 0.76 we fixed it in the release branch but we should fix it for good in main as well.
To solve it I had to fix the circular dependency between .bridge and .uimanager.
I wish I could have isolated the .events package better but as everythign is public, any
change we do is going to be a breaking change so I'm being over cautios here.
