perf c2c report: Add stores related dimension keys
Add 5 stores related dimension key wrappers.
First 3 are to be displayed in the main cachelines overall output:
stores, stores_l1hit, stores_l1miss
The latter 2 are to be displayed within single cacheline output:
cl_stores_l1hit, cl_stores_l1miss
They all display bare numbers of stores for cacheline or its related
offsets.
