Add YAML and error function for MEM_GOODx faults

Add a section to the error and metadata YAML files for the MEM_GOODx
faults. Use that to update/generate a new elog-errors.hpp include file.

Update the power sequencer source to have a memGoodFault function for
handling callouts for MEM_GOODx type errors.
