Flush the WSERV command buffer after deleting a surface.
For graphics systems that use EGL surfaces in the backing store destroying the surface does not guarantee that the memory is immediately freed because this command does not cause a flush. This implies that a manual flush is instead needed. We do this in 2 places; the first is when the surface is destroyed due to a visibility changed. The second case is just after the window has been destroyed. At this point the backing store has already been deleted so the deletion of both the surface and window can happen atomically in WSERV.
