configs: Added list types of replacement policy.

Replacement policy is one of the key points in CPU performance. For ease
of checking the avliable replacment types for any cpu architects,
"replacment policy list" is added in Options.py and ObjectList.py.
Just like Branch Prediction Policies, adding such list would make it efficient for compare cpu performance
regarding different replacment policies especially for Cache.
