This Config configuration will eventually replace the AudioProcessing::noise_suppression() interface. This also introduces a proxy NoiseSuppression, returned by AudioProcessing::noise_suppression. Without this proxy, ApplyConfig could overwrite NS settings for clients who currently use noise_suppression(). For example, the following code will not preserve the noise suppression level: apm->noise_suppression()->set_level(NoiseSuppression::kHigh); auto cfg = apm->GetConfig(); apm->ApplyConfig(cfg); The NoiseSuppression instance returned by noise_suppression() has no way to update the config inside APM, so GetConfig() will return an out-of-date config which is then re-applied. This CL adds a proxy that makes this update, by forwarding Enable() and set_level() calls to ApplyConfig(). Drive-by change: AudioProcessing::Config substructs are reordered to mirror the capture processing pipeline. Tested: Ran ToT and this CL builds of audioproc_f and verified identical settings/aecdumps.
