quickSettings: Add 'subtitle' property
Add a subtitle label to QuickToggle, with a less prominent font. Make the subtitle invisible when no text is present. This new property will be used by next commits to implement quick settings with a static title, and a changing subtitle. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2619>
