patch 9.2.0641: GTK4: crash in gui_mch_menu_hidden()

Problem: GTK4: crash in gui_mch_menu_hidden()
Solution: Skip the sentinel like gui_mch_menu_grey() does
(Yasuhiro Matsumoto).

Menu items use the (GtkWidget *)1 sentinel as their id, but
gui_mch_menu_hidden() only skipped NULL ids and passed the sentinel
to gtk_widget_get_visible(), causing a SEGV.

closes: #20523
