[RN] Make video track fade-in effect cross-platform
Android uses a SurfaceView to render video, which is not quite a View, so the
fade-in animation (which varies the opacity) doesn't work.
Instead, add an opaque black view covering the video, which transitions to
transparent. This creates much smoother transitions on Android, while behaving
the same.
In addition, I removed the flip animation for local tracks, which is no longer
used, since the camera is switched without changing tracks.
