Created an AudioMixer mock in webrtc/api/test.

Created an AudioMixer mock in webrtc/api/test.

The mock is used in a dependent CL https://codereview.webrtc.org/2436033002.

There is also a goal to allow external mixing implementations
(subclasses of webrtc::AudioMixer) and inject them to
PeerConnectionFactory. We think that part of that is an official and
maintained mock.

Summary of changes:
    * Created a mixer mock/stub in webrtc/api/test
    * Made a target webrtc/api:mock_audio_mixer for it.
