audio policy: refactor audio record APIs
Refactor audio policy service APIs controlling audio record (startInput, stopInput, releaseInput)
To allow finer grain control per AudioRecord client and prepare for new concurrent capture
policy
Test: AudioRecord CTS test. manual test of capture use cases:
camcorder, OK Google VoIP
