Smart Radio: don't take "ignore while locked" into account when "power save when screen off" is disabled
QS Tiles: added tile for toggling Smart Radio feature on/off
Useful e.g. when smart radio needs to be temporarily disabled without
need of rebooting a device

Cherry-picked and backported from KK branch
GB Actions: added shortcut for toggling Smart Radio feature on/off
QS Tiles: filter out Smart Radio tile for WiFi only devices
AppPickerPreference: use resource names instead of IDs for alt. icons
We cannot rely on resource IDs since they will most likely change with
each version due to IDs being modified when new resource items are added.
This change requires user to set alt. icons again for their existing
targets/shortcuts.
