Support synchronous onScroll events on the UI thread by using Reanimated

## Describe the feature

Currently the `onPageScroll`, `onPageSelected` and `onPageScrollStateChanged` events are dispatched as bubbling events using the batched bridge. This is really slow and doesn't allow for any smooth (60 FPS) interpolations based on scroll state, such as smooth title changes etc.

I'm suggesting to support synchronous callbacks by using the Reanimated APIs (worklets on the UI thread), which shouldn't be too hard to implement and allow for perfectly smooth 60 FPS animations all without crossing threads and spamming the bridge (see [react-native-gesture-handler](https://github.com/software-mansion/react-native-gesture-handler), they do the same thing with the `onGesture` event.)

## Motivation

* Way better Performance
* No Bridge-spam
* Allow reanimated worklet interpolations with 60 FPS

## Implementation

I wanted to do the same thing for a gyroscope library but haven't come around to actually implement it. I believe reanimated already does a lot of work for you, but I don't exactly know how this is going to work. I'll have to take a look myself, but it [looks like they also just have an `RCTEventDispatcher` set up](https://github.com/software-mansion/react-native-gesture-handler/blob/c2bd377e1fb3c780bb4bea59038b2cadf8ef5624/ios/RNGestureHandlerManager.m#L44), which then simply [sends those events](https://github.com/software-mansion/react-native-gesture-handler/blob/c2bd377e1fb3c780bb4bea59038b2cadf8ef5624/ios/RNGestureHandlerManager.m#L183-L191)... 🤔 So I think there are no native code changes required here, but we somehow need a hook similar to [the `useAnimatedGestureHandler` hook](https://github.com/software-mansion/react-native-reanimated/blob/a8d9720ee5312a43cc4e3beb02e70b2fc6a030ae/src/reanimated2/Hooks.ts#L631-L708).
