Avoid destroying surface before the parent surface stops referencing it.
Add surface sequence numbers, which are used to schedule the
destruction of surfaces. The child surface's destruction can
wait on a set of sequence numbers, and the parent surface can
later queue a frame that satisfies those numbers, causing the
former child surface to be destroyed.
Also move ownership of the SurfaceIdAllocator to the
ui::Compositor, so that the surface id namespace for a
compositor will stay the same across all output surfaces it
ever uses.
