Mac h264: Decode h264 to 4:2:0 instead of 4:2:2

Also remove the OpenGL compatibility key, because it increases power
usage.

This is a slow re-introduction of the previous patch to enable h264
decode to 4:2:0 IOSurfaces, to see where we started causing instability.

This is likely the one that will cause hangs (if not this, then the one that
