The pointer-to-submodule interfaces are being removed. This CL: 1) introduces AudioProcessing::Config::GainController1 with most config, 2) adds functions to APM for setting and getting analog gain, 3) creates a temporary GainControlConfigProxy to support the transition to the new config. 4) Moves the lock references in GainControlForExperimentalAgc and GainControlImpl into the GainControlConfigProxy, as it becomes the sole AGC object with functionality exposed to the client.
