Send SurfaceCreated and SurfaceAboutToBeDestroyed events for wl_surface

Previously, the events were matching the life cycle of QWaylandWindow. This
commit changes it so the events are matching the life cycle of wl_surfaces
instead (a QWaylandWindow can outlive several wl_surfaces).

Some of these events were already sent in QWindowPrivate (the first and last).
Now we handle the cases where the wl_surface is destroyed and recreated due to
hiding/showing the window or when changing the role of the wl_surface.
