Sam Zackrisson 64cdcc0792 AEC3: Add multichannel configuration and multichannel detection
The features have two safety fallbacks:
- multichannel config has a killswitch WebRTC-Aec3SetupSpecificDefaultConfigDefaultsKillSwitch
- stereo detection has a killswitch WebRTC-Aec3StereoContentDetectionKillSwitch

Both features are enabled by default in the AEC3 config.

Tested: Bitexact on a large number of aecdumps.
