Summary:
This is a Fabric-compliant implementation of `JSResponder` feature. To make it work e2e we also need to update FabricRenderer in React repository. But before we can do this, we need to ship the native changes.

Summary:
Normally, UIScrollView adjust `contentOffset` inside `setContentSize` to prevent over-scroll. In most cases, it works fine but in a case when the ScrollView is in the middle of user interaction the over-scroll is perfectly acceptable. So, to work around this issue we disable `setContentOffset` when we update `contentSize` and the gesture interaction is in progress.

Summary:
This replaces the internal core implementation of `setState` with the new `updateStateWithAutorepeat` which is now the only option.
In short, `updateStateWithAutorepeat` works as `setState` with the following features:
* The state update might be performed several times until it succeeds.
* The callback is being called on every retry with actual previous data provided (can be different on every call).
* In case of a static value is provided (simple case, not lambda, the only case on Android for now), the same *new*/provided value will be used for all state updates. In this case, the state update cannot fail.
* If a callback is provided, the update operation can be canceled via returning `nullptr` from the callback.
This diff removes all mentions of the previous state update approach from the core; some other leftovers will be removed separatly.

Summary:
This is the first implementation stage of on-demand child views mounting for <ScrollView> feature.
It works this way. When mounting layer requests mounting of a subview of <ScrollView>, the component does not mount it immediately. Instead, it stores it in an internal collection, and then after the transaction finishes use that to mount views that are in a visible area.
Then we re-evaluate which child views are should be mounted and unmounted on every significant onScroll event. We use some leeway to do it not so often to save CPU cycles on scrolling.
This feature already works fine but to make it shippable we need to integrate it with an `overflow inset` feature to make it 100% reliable in complex cases when some views have overflow content.

Summary:
This diff disables the feature that propagates ScrollView's content offset to ShadowNode hierarchy making measuring content-offset-aware.
Seems that feature breaks FlatList because it does not expect measure calls to be content-offset-aware. We need to validate which legacy `measure*` calls should be content-offset-aware and which should not, and then verify that actual feature works (it's not clear why it worked with FlatList before) well before re-enabling this.
For now, the most safer choice is to disable this feature because I don't think some call sites actually rely on it now.

Summary:
This diff moves the delegate splitter from RCTScrollViewComponentView class to RCTEnhancedScrollView. Now, it's a key feature of RCTEnhancedScrollView.
We need this to make `delegate` property of our UIScrollView subclass as resilient to any abuse as possible. E.g., if some other part of the app, unrelated to RN (e.g. BottomSheet component), nils the property, all dependent RN specific infra should continue to work. To make it possible, we make an exposed property to use the internal delegate splitter instead of providing direct access to the property of a superclass.

Summary:
Setting minimal throttle to 1/60 causes dropped updates.
Let's take following example
Each frame is 16.666 MS.
Frame1: [________didScroll is called towards end of the frame_]
Frame2: [_didScroll is called towards beginning of the frame_________]
update from Frame 2 doesn't propagate because we set throttle to 16MS thinking that `onScroll` is called for each frame.
If Javascript specified value below 1/60 it is basically asking for every update.

Summary:
In some cases, the view class is the only that retains stored `props_` variable. At the same time the `[super updateProps:props oldProps:oldProps];` actually resets the pointer with a pointer to new props value which sometimes causes the deallocation of the old value. All that is okay unless the implementation of `updateProps:oldProps:` in superclasses stores a raw reference to an old value in the very beginning of the method (for convenience and perf reasons).
So, to prevent preliminary deallocation of the old value pointed by `_props` we moved all `[super updateProps:props oldProps:oldProps];` calls to the end of overloaded methods.
