monitor-manager: Expose :night-light-supported property

Browse source 
We currently only expose this information over D-Bus, but now
gnome-shell needs it as well for the corresponding quick settings
toggle.

We don't want to talk D-Bus to ourselves, so make the information
available as a property as well.
