clutter/text: Use new pango API to compare attribute lists

Browse Source 
Use the new API provided by Pango to compare two PangoAttrLists, this
means we can also detect equal lists that were newly created and avoid
the expensive relayout of the ClutterText a lot more often.

Depends on https://gitlab.gnome.org/GNOME/pango/merge_requests/172

Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1411
