perf/x86/intel/rapl: Utilize event->pmu_private
Store the PMU pointer in event->pmu_private and use it instead of the per CPU data. Preparatory step to get rid of the per CPU allocations. The usage sites are the perf fast path, so we keep that even after the conversion to per package storage as a CPU to package lookup involves 3 loads versus 1 with the pmu_private pointer.
