CTA2075: add client/server logic for codec loudness management

Changed the LoudnessCodecFormat name into LoudnessCodecInfo and removed
the setAudioTrack method. The new API will provide the corresponding
AudioTrack in the startLoudness updates methods.

Test: adb shell device_config put media_audio android.media.audio.loudness_configurator_api true
