Add and direct implementors to use LowBatteryStatusAccessory
BatteryAccessory is used only by BatteryService and does not apply to MotionSensor, SmokeSensor, etc. Deprecate BatteryAccessory and leave the implementation for BatteryService / Battery for a future date. Log a warning for accessories that are still trying to use it.
