Ravi Bangoria a2eba90326 perf/mem: Rename PERF_MEM_LVLNUM_EXTN_MEM to PERF_MEM_LVLNUM_CXL 
PERF_MEM_LVLNUM_EXTN_MEM was introduced to cover CXL devices but it's
bit ambiguous name and also not generic enough to cover cxl.cache and
cxl.io devices. Rename it to PERF_MEM_LVLNUM_CXL to be more specific.

Ravi Bangoria 08830e9d2f perf/uapi: Define PERF_MEM_SNOOPX_PEER in kernel header file 
PERF_MEM_SNOOPX_PEER is defined only in tools uapi header. Although
it's used only by perf tool, not defining it in kernel header can
create problems in future.

Ravi Bangoria 1022f26d04 perf/mem: Introduce PERF_MEM_LVLNUM_{EXTN_MEM|IO} 
PERF_MEM_LVLNUM_EXTN_MEM which can be used to indicate accesses to
extension memory like CXL etc. PERF_MEM_LVL_IO can be used for IO
accesses but it can not distinguish between local and remote IO.
Introduce new field PERF_MEM_LVLNUM_IO which can be clubbed with
PERF_MEM_REMOTE_REMOTE to indicate Remote IO accesses.
