BT: API to update quiet mode status in Adapter service [1/3]

 - In BLE on use case, quiet mode status is not updated to
   Adapter service which results in not initiating auto
   connection of hfp & a2dp though quiet mode is disabled
   for next turn On.

 - Added new API to update quiet mode status in Adapter
   service.
