[gtk+] gdk/win32: Fix build after GdkScreen and cursor cleanups

[Chun-wei Fan <fanchunwei src gnome org>]

commit 6a12a3cd10c9985d2dbbf176e6899b54880e14dd
Author: Chun-wei Fan <fanchunwei src gnome org>
Date:   Fri Nov 3 16:37:18 2017 +0800

    gdk/win32: Fix build after GdkScreen and cursor cleanups
    
    Move the leftovers from the removals to use the current APIs, to fix the
    build.  Also for gdk_device_virtual_set_window_cursor(), only do
    something when a valid GdkCursor is passed in here.
