Laying down the groundwork for GPU video layers.

This gets --enable-video-layering working when using the GPU backing store.  No actual visuals yet, just IPC message passing and a lot of NOTIMPLEMENTED messages.

BUG=33329
TEST=try it out and see if you get lots of NOTIMPLEMENTED messages corresponding with video playback
