Summary
This PR fixes a bug on Android where taps sometimes incorrectly trigger while swiping between pager screens, see issues #960 and #954. These issues in turn were opened in order to investigate bluesky-social/social-app#7312
The cause of the bug seems to have had to do with React not being notified when the native pager starts scrolling, which meant that it didn't properly cancel gestures in the pager's children.
The fix involves adding a call to notifyNativeGestureStarted, whose purpose is exactly to notify JS that a native gesture has started so it can dispatch the appropriate cancel events, see its use in other similar components like ReactScrollView
This call was added to NestedScrollableHost, where scrolling canceling logic was already present, however the behavior of nested scrollables should hopefully remain unchanged.
Test Plan
I have tested the issues this PR aims to solve (#960, #954, bluesky-social/social-app#7312) and I cannot reproduce the described bugs anymore.
I have also tested all the examples in the repo, and all seem to function as expected. In particular, examples with scrollables (eg. ScrollViewInsideExample) or nested pagers (eg. NestPagerView) seem to be unaffected.
