Genki Kondo 03f70bf995 When animating using native driver, trigger rerender on animation completion (#37786)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37786

When using the native driver for animations that involve layout changes (ie. translateY and other transforms, but not styles such as opacity), because it bypasses Fabric, the new coordinates are not updated so the Pressability responder region/tap target is incorrect.

Prior diffs ensure that upon completion of natively driven animations, the final values are synced to the JS side AnimatedValue nodes. In this diff, on completion of a natively driven animation, AnimatedProps.update() is called, which in turn calls the value update callback on AnimatedProps, which [triggers a rerender (via setState)](https://www.internalfb.com/code/fbsource/[566daad5db45807260a8af1f85385ca86aebf894]/xplat/js/react-native-github/packages/react-native/Libraries/Animated/useAnimatedProps.js?lines=80) which has the effect of pushing the latest animated values to Fabric.

Alternative considered was using setNativeProps, but that approach was dropped as setNativeProps was only introduced to make migration easier and should not be used for new code, as per sammy-SC.

Changelog:
[General][Fixed] - When animating using native driver, trigger rerender on animation completion in order to update Pressability responder regions
