lib/nhlt, soc/intel/skl: Update NHLT to program feedback config 

Adapted from WIP (and abandoned) patch CB:25334, this patch:

1. Ensures SSP endpoint InstanceId is 0
2. Adds capability_size parameter at the end of the nhlt
3. Adsd more config_type enum values to accommodate feedback stream
4. Programs virtual_slot values for max98373, max98927,
   and rt5514 nhlt files
5. Adds NHLT feedback_config parameters

Default feedback configs are added here to the max98373, max98927, and
rt5514 codecs; in a follow-on patch, these will be overridden at the
board level.

TEST=tested with subsequent patch
