Fix AnimatedEvent leaking topScrollEnded handler (#46576)

Summary:
Pull Request resolved: #46576

We automatically add this handler in `addAnimatedEventToView` but we do not remove it in `removeAnimatedEventFromView`, which causes us to leak it. This is especially bad as we attach and detach the event handler multiple times while rendering.
