Subject: [RFC v2 3/5] perf jevents: Add support for parsing perchip/percore events

Added the "PerChip" field  in enum so that perf knows they are
per chip events.

Added the "PerCore" field in enum so that perf knows they are
per core events and add these fields to pmu_event structure.

Similar to the way we had "PerPkg field
to specify perpkg events.
