Disables multidevice support in GDK. This call must happen prior
to gdk_display_open(), gtk_init(), gtk_init_with_args() or
gtk_init_check() in order to take effect.
Most common GTK+ applications won’t ever need to call this. Only
applications that do mixed GDK/Xlib calls could want to disable
multidevice support if such Xlib code deals with input devices in
any way and doesn’t observe the presence of XInput 2.
