ui/gtk: use native keyboard scancodes on Windows

Browse source 
Since GTK 3.22 the function gdk_event_get_scancode() is
available. On Windows this function returns keyboard scancodes
and some extended flags. These raw keyboard scancodes are much
better suited for this use case than the half-cooked win32
virtual-key codes because scancodes report the key position on
the keyboard and the positions are independent of national
language settings.
