Series selftests/resctrl: Fixes, cleanups, and rewritten CAT test |

Commit Message

  CAT and CMT tests have count_of_bits, long_mask, and cache_size global
variables that can be moved into the sole using function.

Make the global variables local variables of the relevant function to
scope them better.
