Mac h264: Use GLImageIOSurface to bind frames to textures

A framework for binding IOSurfaces to textures was added after accelerated
h264 decode landed. Move the accelerated h264 code over to using this
path.

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.

Small patch (that you previously saw in
https://codereview.chromium.org/1822173002/).

I'm putting money on there being OpenGL <-> VideoToolbox deadlocks that we'll
have to carefully avoid ...
