Original change's description:

>
> This CL is 3/3 in effort to fix the regressions caused by sending
> unneeded compositor frames.
>
> This CL provides a signal from the SurfaceLayerImpl to the VideoFrameSubmitter
> to prevent compositor frames from being sent at undesired times (occlusion, not
> being added into the layer tree).
