Subject: [RFC 3/3] perf/tools/pmu_events/powerpc: Add hv_24x7 core level metric events

This patch adds hv_24x7 core level events in nest_metric.json file
and also add PerChip/PerCore field in metric events.

Result:

power9 platform:

command:# ./perf stat --metric-only -M PowerBUS_Frequency -C 0 -I 1000
     1.000070601                        1.9                        2.0
     2.000253881                        2.0                        1.9
     3.000364810                        2.0                        2.0
