[LyX/master] Remove Language::fontenc()

[Juergen Spitzmueller]

commit f63de41c4c2180705b44c3444718d7f35df89b8a
Author: Juergen Spitzmueller <sp...@lyx.org>
Date:   Mon Apr 23 12:59:57 2018 +0200

    Remove Language::fontenc()
    
    This raw vector of fontenc alternatives is not needed outside Language,
    and it should actually never be used.
