Keep quick settings brightness icon/dialog level in sync.

We now listen for brightness changes and update the icon appropriately.
Note there are still only two icon states in QS (auto-on and auto-off).

We also listen for user switches, since the brightness setting is per-user.

The manual brightness level is now kept in sync with level set in Settings.

This change is tightly scoped to brightness only.  Any other
QS bugs should be triaged separately.
