Adapt to split clutter/pango

In https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4106, all of
the fonts rendering related bits are now behind a build option and under
a different header.

So we bail out if mutter was built without it & make sure we include the
new clutter-pango header where needed.
