perf powerpc: Add data source encodings for power10 platform
The code represent memory/cache level data based on PERF_MEM_LVL_*
namespace, which is in the process of deprication in the favour of newer
composite PERF_MEM_{LVLNUM_,REMOTE_,SNOOPX_,HOPS_} fields. Add data
source encodings to represent cache/memory data based on newer composite
PERF_MEM_{LVLNUM_,REMOTE_,SNOOPX_,HOPS_} fields.
Add data source encodings to represent data coming from local
memory/Remote memory/distant memory and remote/distant cache hits.
Inorder to represent data coming from OpenCAPI cache/memory, we use
LVLNUM "PMEM" field which is used to present persistent memory accesses.
Result in power10 system with patch changes:
