Android Java Surfaces can now be looked up via GpuSurfaceTracker

AndroidVideoDecodeAccelerator needs to be able to retrieve
registered Surfaces in order to decode to them. Previously this was
only possible to do from the GPU process through
SurfaceTextureManagerImpl, but now it can be done from the browser
through GpuSurfaceTracker. This enables fullscreen video decoding with
AVDA when in-process-gpu is enabled.

Do we need to merge this to m51 to ensure fullscreen works on these devices?

Oops, yeah

Your change meets the bar and is auto-approved for M51 (branch: 2704)
