Jaswinder Singh Rajput 5095f59bda x86: cpu_debug: Remove model information to reduce encoding-decoding
Remove model information, encoding/decoding and reduce bookkeeping.

This, besides removing a lot of code and cleaning up the code, also
enables these features on many more CPUs that were enumerated before.
