perf/x86/intel: Initialize architectural PEBS
arch-PEBS leverages CPUID.23H.4/5 sub-leaves enumerate arch-PEBS
supported capabilities and counters bitmap. This patch parses these 2
sub-leaves and initializes arch-PEBS capabilities and corresponding
structures.
Since IA32_PEBS_ENABLE and MSR_PEBS_DATA_CFG MSRs are no longer existed
for arch-PEBS, arch-PEBS doesn't need to manipulate these MSRs. Thus add
a simple pair of __intel_pmu_pebs_enable/disable() callbacks for
arch-PEBS.
