compositor: make set_frozen a vfunc

Browse Source 
MetaSurfaceActor can be made "frozen" via it's set_frozen method.

That method could be useful as virtual function, so that the wayland
subclass can tie into it and freeze the underlying surface.

This commit does the prerequiste work of making set_frozen a vfunc.
A future commit will change the wayland subclass code to leverage
the vfunc.
