Add system/DSP AEC logic to audio_manager_cras
Enable CrAS-based System AEC/APM on LaCrOS by porting the existing logic from audio_manager_chromeos to audio_manager_cras. To be specific the functions covered in two prior CLs: (1) https://chromium-review.googlesource.com/c/chromium/src/+/2782443 Allow Chrome to talk to Chrome OS to enable audio processing functionalities (AEC, AGC, NS) in CrAS. Through new flags via finch experimentation. (2) https://chromium-review.googlesource.com/c/chromium/src/+/3475131 Adds the control logic in Chrome to provide finch-control over the AEC, NS and AGC, DSP effects in CrAS, allowing safe fallbacks to the browser counterparts.
