[GTK3] Improve the resize -> hide -> show scenario

Browse source 
* src/gtkutil.c (xg_frame_set_char_size)
(xg_frame_set_size_and_position): Call gtk_window_resize for
child frames too, to record _GtkWindowGeometryInfo#resize_width
and resize_height.  They are later looked up by
gtk_widget_show_all in x_make_frame_visible (bug#80662).
Without this the widgets go back and forth between the
remembered and actual sizes after make-visible.
