CTA2075: Optimize data sent to client

Aggregate bundles that are similar to multiple MediaCodecs and use the
LoudnessCodecInfo as aggregation key.

Removed mediaCodecHash attribute from LoudnessCodecInfo to allow
aggregation of multiple audio codecs which can use the same loudness
parameters

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