[mutter] context: Move the signal handling and dir management to user

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

commit 8a4aa92a5406212225b359c3d2f99f3f8f84e17e
Author: Jonas Ådahl <jadahl gmail com>
Date:   Fri Jul 2 17:18:51 2021 +0200

    context: Move the signal handling and dir management to user
    
    Signals and changing current directory is a process global action, thus
    isn't that suitable for a library. Thus, move that responsibility to
    gnome-shell.
