Currently, the window actor freeze/thaw implementation sets the frozen state of the surface actor using `meta_surface_actor_set_frozen()`. If we want to expand that behavior to also freeze/thaw commits for X11 windows running on Xwayland, we need to have a specific vfunc to abstract that in the window actor specific implementation. https://gitlab.gnome.org/GNOME/mutter/merge_requests/942
