[Master port]Add new audio sources for audio capture

This patch ports a change to the HAL interfaces done in master in
order to have the same Audio common HAL interface in both AOSP and master.
This is needed as the Bluetooth HAL uses the audio common HAL and needs
to be frozen in the same state in both AOSP and MASTER.

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.

Test: CTS tests for audio capture
