AudioService: Add Hearing Aid Switch Control

1) Add setBluetoothHearingAidDeviceConnectionState interface to control
suppressNoisyIntent flag.
2) Add check to confirm the previous device is active or not when want
to clean it.

Bug: 112279820
Test: Build Pass, BT off/on when play A2DP, Switch active device
