Olivier Fourdan aa017383ac window-actor: Add set_frozen vfunc
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.
