    gtkwindow: run ::event and specific handlers for EWMH action triggering events
    
    This gives an opportunity for implementations to handle these events
    differently, instead of hardcoding the WM-triggering behavior.
    
    gtk_window_event() only forwards events for WM management if the event
    widget is not the window (ie. caught when bubbling), so is safe to be
    called here without triggering gtk_window_handle_wm_event() twice.
    
    This commit is an adaption to master of
    https://bugzilla.gnome.org/show_bug.cgi?id=736702#c1 by Cosimo Cecchi.
