    gtkfontchooserwidget.c: Fix builds without PangoFT2
    
    We need to build the bits that use PangoFT2 only if PangoFT2 is present, and
    for now since get_language_names() assumes the use of ISO codes and is
    currently only built with PangoFT2 is present, don't use it if PangoFT2
    does not exist.
    
    Add a TODO to add a Windows version of get_language_names() that uses
    Windows APIs instead of using ISO codes.
