Fix incorrect GTK menus on HiDPI monitors with scaling factor > 1
This should fix Bug#31223, Bug#28106, Bug#23672 as well as Ubuntu bug https://bugs.launchpad.net/ubuntu/+source/emacs25/+bug/1695228 Also fixes the formerly unscaled Y value returned by frame-monitor-workarea (and display-monitor-attributes-list). For details on why some GTK menus were empty please see thread https://lists.gnu.org/archive/html/emacs-devel/2019-11/msg01061.html * src/gtkutil.c (menubar_map_cb, xg_update_frame_menubar): Scale up req.height so that the menu bar's height is in device pixels as expected. (xg_event_is_for_menubar): Scale down rec.x and rec.y so that gtk_widget_intersect() works as intended. * src/xfns.c (Fx_display_monitor_attributes_list): Scale work.x and work.y up to be in device pixels.
