Sam Zackrisson 1397c4bfd9 AEC3: Handle temporary stereo content more robustly 
During temporary stereo content when the AEC3 uses a mono reference signal, the signal is downmixed by averaging instead of using only the left channel.

Additionally, temporary stereo content is flagged as an echo path change.

Tested: Modified local build: Verified stereo mode entered / left in accordance with hysteresis and timeout thresholds. Verified temporary stereo detected during temporary stereo playout. Made an aecdump and inspected content.
Bug: chromium:1295710
