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.
