This allows us to inject a videoFrameProcessorFactory into
MediaCodecVideoRenderer, without issues about creating the
VideoFrameReleaseControl in the MediaCodecVideoRenderer.
Unfortunately, this does result in more complex CVSP state, where
VideoFrameReleaseControl is no longer final, may be null, and may potentially
change. However, this tries to be careful with assertions to guarantee good
state, and is cleaner than modifying the long-standing MediaCodecVideoRenderer
interface.
Tested that this works on the ExoPlayer demo with setVideoEffects applied, and
using a playlist with SDR->HDR and HDR->SDR items.
