mutter: Add signal handlers
With the introduction of MetaContext, the responsibility for handling signals was changed to the application (e.g. GNOME Shell) using libmutter. What wasn't fixed was making the stand-alone mutter do the equivalent as well. This commit fixes this. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2007>
