When performing isKindOfClass checks, we were occasionally looking up the class in question using NSClassFromString(), instead we now check against the class directly, which has the added benefit of being type-safe, and not succeptible to string typos.

Moves the declaration of ForwardingGestureRecognizer and FlutterDelayingGestureRecognizer to the FlutterPlatfomViews_Internal.h header, which is non-public.

LGTM. I assume we started using CAMetalLayer before it was available in an SDK in CI? 🤷🏻
