perf mem: Add 'cache' and 'memory' output fields

This is a breakdown of perf_mem_data_src.mem_lvl_num.  But it's also
divided into two parts because the combination is bigger than 8.

Since there are many entries for different cache levels, 'cache' field
focuses on them.  I generalized buffers like LFB, MAB and MHB to L1-buf
and L2-buf.

The rest goes to 'memory' field which can be RAM, CXL, PMEM, IO, etc.

  $ perf mem report -F cache,mem,dso --stdio
