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.
