Let's document the parameters of these commands, so we can remove them
from the "documentation-exceptions" list.

While at it, extend the "Returns:" documentation as well, fixing a wrong
use of CpuModelBaselineInfo vs. CpuModelCompareInfo for
query-cpu-model-comparison.

Agreed to both. Do you want to fixup when applying or do you prefer a v2?

Thanks!

Happy to fix it up myself, thanks!
