After some thought, we decided we don't need the flexibility of
separate horizontal and vertical props - it would be much nicer
to just have a single prop for the edge length and then the native
code can enable the booleans as appropriate.

Summary:
This PR adds support for custom `StickyHeaderComponent` to be used in ScrollView (and by extension in FlatList, SectionList..).
Motivation: I've been working on a FlatList with hidable header that has a search field in it. Something like https://medium.com/appandflow/react-native-collapsible-navbar-e51a049b560a but using a FlatList w/ pull-to-refresh. The implementation can be found at https://snack.expo.io/vonovak/hidable-header-flatlist .
I used the `ListHeaderComponent` prop to render the custom header - as opposed to absolute positioning which is used in the linked article because I also need the loading indicator (I added `refreshing` and `onRefresh` for that) to show up above the header.
I proceeded by adding `stickyHeaderIndices={[0]}` to keep the header at the top, which seems to be the idiomatic way to do so. Then I added `Animated.View` with custom translation logic to the rendered header.
All appears to be working fine at the first sight - when you tap any item, you'll see it react to touch (red underlay). You'll also see the header becomes hidden if I scroll far enough and appears again after scrolling up. BUT - when you scroll down so that the header becomes hidden and tap the first visible item in the list, it will not react to touches! The reason is that `ScrollViewStickyHeader`
https://github.com/facebook/react-native/blob/9a84970c35d22b68fb3d8eac019c7f415a14c888/Libraries/Components/ScrollView/ScrollView.js#L984
has its own translation logic and when I tap onto the item at the top of the list, it seems like I'm tapping the item but I'm in fact tapping that `ScrollViewStickyHeader`.
I tried working around this by not specifying `stickyHeaderIndices={[0]}` and using `ListHeaderComponentStyle` prop (this needed some additional changes in https://github.com/facebook/react-native/blob/9a84970c35d22b68fb3d8eac019c7f415a14c888/Libraries/Lists/VirtualizedList.js#L786, and the animation is junky for some reason - as if the header always needed to "catch up" with the scroll offset, causing jitter) and `CellRendererComponent` (junky animations too), but concluded that allowing to specify custom `StickyHeaderComponent` is the cleanest way to make something like this work. I'm slightly surprised I needed to do all this to make such a usual pattern work - am I missing something?

Summary:
Fixes#22752
On line 1021 you are passing base style to props:
`style: [baseStyle, this.props.style],`
Explicitly passing base style to ScrollView just overrides this line and doesn't let developers to customise style of any inheritors of ScrollView (not only FlatList) with custom RefreshControl.
So this line (1113) seems to be removed.

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.

Summary: For some reason the scroll events are sometimes generated with highly irregular spacing, some coming less than a millisecond apart. For interactions that must track scrolling exactly, this can cause them to glitch. With a scroll throttle of less than 17 ms, the intention is clear that the UI should be updated in sync with the scroll view so we shouldn't drop any events.

Summary:
Would like feedback from the community as this may not be the best solution for all
I would like to restrict (or paginate) the fling of a horizontal ScrollView when `snapToInterval` is set. This is not currently possible with `pagingEnabled`, since the pagination works only when items are the entire width of the ScrollView.
This implementation simply restricts the predicted `targetOffset` found from the `x` velocity and replaces it with the offset when the pan gesture ended.
To get pagination working, I may paginate based on the interval by calculating the offset delta from the beginning of the gesture to current offset and restricting the scrolling behavior to the `snapToInterval`. If this is preferred, I can update this PR or make a new one, but wanted to start a discussion since it seems like there are many in the community that would like this feature #21302 .

Summary:
ScrollView's scrollTo behavior on iOS was recently changed to limit the offset to the content size plus any content inset (see #23427). This departure from the old behavior created UI issues for anyone that is using the over-scroll ability for the purpose of positioning elements at specific coordinates on the screen. Examples include using this behavior to position TextInputs above the virtual keyboard programmatically when focused or moving drop down elements positioned near the bottom of the content toward the top of the screen when selected to show a larger absolutely positioned item list. Default behavior does not change and this is an "opt-in" type of prop to re-enable the old behavior.

The ScrollView component seems to have been written for a default touch up / touch down scrolling behavior. However, when using snapToInterval, this default behavior of adding PanResponders while the ScrollView is animating or has an active touch causes bugs with the PanResponder hijacking touches it is not supposed to hijack.

Summary:
Motivation:
----------
This is one of the more sought after feature requests for RN:
react-native.canny.io/feature-requests/p/add-speed-attribute-to-scrollto
This PR adds the support to add a "duration" whenever using "scrollTo" or "scrollToEnd" with
a scrollView. Currently this only exists for Android as the iOS implementation will be somewhat more involved.
This PR is also backwards compatible and does not yet deprecate the "animated" boolean. It may not make sense to ever deprecate "animated", as it could be the flag that is used when devs want the system default duration (which is 250ms for Android). I'm not sure what it is for iOS. It would simplify things to remove "animated", though.

Summary:
This PR exposes the `onScrollToTop` event on iOS using the same event-forwarding infrastructure as other ScrollView events. (As such, its `nativeEvent` object reflects the same fields as other ScrollView events.)
Motivation:
----------
If your app is only interested in knowing the position of a ScrollView after a scroll has completed, it can use `onScrollEndDrag` and `onMomentumScrollEnd` to inspect the `contentOffset` after a drag-initiated scroll has finished. (This is much less expensive than observing the `onScroll` event if you only want to know the end position.) However, neither of these `End` events fire if the ScrollView is scrolled to the top by tapping the status bar.
By exposing `onScrollToTop`, it is now possible for an app to cheaply know when such a scroll has completed.
