    window-actor: Don't freeze actor updates during the size-change effect
    
    As explained in the last commits, we'll let gnome-shell take care of
    this since freezing and thawing needs to be decoupled from the effect
    starting and ending.
    
    So stop freezing the MetaWindowActor when starting the effect and
    thawing the actor when ending the effect.
