return final animation values to JS when animation completes

Summary:
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

**This diff:**
- Returning the final values from the native side, at the same place it sets the "finished" flag. This gets sent to JS in `animated/animations/Animation.js`. In this diff I'm passing the value when 'hasFinishedAnimations' is true, but in a follow up diff I will look into other cases such as cancelled animations

Next:
2. Update the Animated.Value to reflect the new values
3. Call the onEnd function if there is one set
4. Use `setNativeProps` to pass the new values down for layout calculations and the correct Pressability responder region

Changelog:
[General][Internal] - return animated values to JS for natively driven animations
