Reduce observers in SystemUI: StatusBarIconView

Currently, for each status bar icon view there is a observer that
listens for changes of STATUS_BAR_NOTIF_COUNT. With one
notification usually having one or more status bar icons
you may end up easily with 10+ more observers for ~5 notifications.

With this commit the internal observer class becomes a singleton.
This means there is now only one observer for all status bar icons
and additional binder calls on new notification are avoided.

Improve auto-brightness handling

- Add a setting to control the auto-brightness algorithm responsitivity
- Make the algorithm react much faster when the ambient brightness
  increases quickly, e.g. when receiving a call in bright sunlight.

profiles: Broadcast profile updates

Add broadcast to indicate profile changes that does not
cause a profile to be selected.

Use the new broadcast to update the Profile Tile more
reliably.

Currently the tile update is triggered by a profile
selection. However, the active profile may change without
triggering a selection. This happens, for instance, on
locale changes.

The Profile Tile does handle locale changes, but is subject
to a race condition. If it handles the locale change before
the profile manager does, the name change will not be seen.
