    Gio::SimpleAction: Make set_state() public
    
    This is needed to apply the requested state in a custom handler for
    signal_change_state(). It was protected on an assumption that when the C
    doc for g_simple_action_set_state() said “This should only be called by
    the implementor of the action”, it meant the implementor of a subclass.
    
    But the C docs for signal change-state are clear that it means the
    implementor of the signal handler. Without such a user being able to
    call set_state(), they can’t apply the new state, unless they subclass
    SimpleAction, which is a lot to require for such a simple case as this.
