    GtkApplicationX11: read the startup ID from the platform data
    
    If the platform data passed with actions and activations includes
    a startup notify ID, we should read it and pass it down to GDK.
    This ensures that the right startup notify is completed after the
    signal emission, and that the user time of the GdkDisplay is properly
    updated (which in turn makes sure the windows are not subjected
    to focus-stealing-prevention)
