GL: Add extensions to enable hardware video decode on Android.

The Android SurfaceTexture API has to be initialized with a texture id
which Chrome has to query from an ANGLE external texture. It also
rebinds and sets the texture dimensions on calls to
SurfaceTexture.updateTexImage so ANGLE must be notified about these
changes so that state tracking and validation continue to function.
