sound: Include sound(4) channel information in sndstat nvlist

Description

sound: Include sound(4) channel information in sndstat nvlist

Extend SNDST_DSPS_PROVIDER_INFO for sound(4) to include information
about each channel in a given device, similar to how cat'ing
/dev/sndstat with hw.snd.verbose=2 works.

While here, document all provider_info fields.
