DnD quick setting states

We now have a quick setting for changing the feedbackd profile. Feedbackd has 3 possible states

• Full (audio + haptic)
• Quiet (haptic only)
• Silent (no audio, no haptic)

Since all other the toggles in the shell are two-state on/off switches, this three-state setting doesn't fit in very well. The Full/Quiet/Silent wording is also not something I'd expose as-is in the UI, as it isn't immediately clear what these mean in this context.

I'd suggest the following for now:

• Toggle between silent and whatever non-silent mode was last configured (either full or quiet). This would be complicated by the fact that we don't have GUI settings for this yet, so there'd be no other way to toggle it for the moment. Personally I think it could be fine to just go with Full/Silent only for now.
• Use the labels "On" for Full, "Quiet" for Quiet, and "Do not Disturb" for Silent
