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.
