[gtk+] API: Remove gdk_screen_get_width() and gdk_screen_get_height()

[Benjamin Otte <otte src gnome org>]

commit 0be88cc76e756ee96839273117b464ab21a4f708
Author: Benjamin Otte <otte redhat com>
Date:   Fri Sep 9 14:53:18 2016 +0200

    API: Remove gdk_screen_get_width() and gdk_screen_get_height()
    
    ... and gdk_screen_get_width_mm() and gdk_screen_get_height_mm() and
    the shortcut counterparts that call these functions on the default
    screen.
    
    Modern display servers don't provide an ability to query the size of a
    screen or display so we shouldn't allow that either.
