add new audio sources for audio capture
This commit adds the following audio capture sources:
- AUDIO_SOURCE_VOICE_PERFORMANCE: for real time live performances like Karaoke.
- AUDIO_SOURCE_ECHO_REFERENCE: for capturing the reference signal to suppress by an echo
canceller. Protected by privileged permission CAPTURE_AUDIO_OUTPUT.
Also added device AUDIO_DEVICE_IN_ECHO_REFERENCE selected when the requested
capture source is AUDIO_SOURCE_ECHO_REFERENCE.
