    clutter: Demote the new clutter_stage_grab() precondition check
    
    There do indeed seem to be places in our own code that trigger grabs on
    actors before they are realized. It was not the intention to change the
    practical preconditions for GNOME 43, so make it an even lower minimum
    that every caller ought to match: That the actor is attached to the stage.
    
    Further constraining of these preconditions will have to wait until
    branching for new development.
    
    Fixes: 9c79c7234 (clutter: Only allow grabs to be created on realized actors)
