audio: porting MAXXAUDIO
- use effect module to monitor stream's volume
- the control(maxxaudio) monitors active device and
changed volume from HAL, and send audio calibration
to acdb via acdb_loader.
- support specific USB headset
Enabled function:
- LR channels swap
- load external tuning table for volume preset feature
Bug: 74360112
Test: manual effect test, usb headset test
Change-Id: I9b35436d6abebcfa250beb4857dfa0be9248f2b5
