    wayland/actor-surface: Set geometry scale in surface actor
    
    Now that MetaShapedTexture is a ClutterContent implemetation that
    is aware of its own buffer scale, it is possible to simplify the
    event translation routines.
    
    Set the geometry scale in MetaSurfaceActor, and stop adjusting the
    surface scale when translating points. Also remove the now obsoleted
    meta_wayland_actor_surface_calculate_scale() function.
