audio: ble: volume computation improvement on BLE for notifications 



BLE should behave the same as A2DP in this scenario.
When playing STRATEGY_SONIFICATION* streams, or system sounds or
  enforced sounds on A2DP/BLE during media playback, ensure the
  difference between the media volume and the notification
  is no more than 12dB.
