perf powerpc: Add encodings to represent data based on newer composite PERF_MEM_LVLNUM* fields

The code represent data coming from L1/L2/L3 cache hits based on
PERF_MEM_LVL_* namespace, which is in the process of deprecation in the
favour of newer composite PERF_MEM_{LVLNUM_,REMOTE_,SNOOPX_,HOPS_}
fields.

Add data source encodings to represent L1/L2/L3 cache hits based on
newer composite PERF_MEM_{LVLNUM_,REMOTE_,SNOOPX_,HOPS_} fields for
power10 and older platforms

Result in power9 system without patch changes:
