perf c2c report: Add hitm related dimension keys 

Adding 5 hitm related dimension key wrappers.

First 3 are to be displayed in the main cachelines overall output:

  tot_hitm, lcl_hitm, rmt_hitm

The latter 2 are to be displayed within single cacheline output:

  cl_rmt_hitm, cl_lcl_hitm

They all display bare numbers of remote/local/total HITMs for cacheline
or its related offsets.
