[mutter] Remove meta_quit()

[Marge Bot <marge-bot src gnome org>]

commit 6768b509ea11f1c4cf84fc107202a0a4862daa65
Author: Jonas Ådahl <jadahl gmail com>
Date:   Wed Mar 3 17:26:47 2021 +0100

    Remove meta_quit()
    
    It is no longer used, so remove it. This also removes the intermediate
    MetaContext global singleton, as it is no longer needed.
