Add way to mark other Surface a predecessor for a Surface.

Add way to mark other Surface a predecessor for a Surface.

Previously-unseen Surfaces are always treated as being completely
damaged. However, sometimes it makes sense to essentially clone a
Surface with a new SurfaceId for synchronization. In those
circumstances, it's possible to treat the damage of the first frame of
the new Surface as being against the last frame of the old Surface, so
add a way to signal that.
