Lioncash 0e1b5acc6a audio_core/audio_renderer: Name previously unknown parameters of AudioRendererParameter
Provides names for previously unknown entries (aside from the two u8
that appear to be padding bytes, and a single word that also appears
to be reserved or padding).

This will be useful in subsequent changes when unstubbing behavior related
to the audio renderer services.
