perf/x86/intel: Add CPUID enumeration for the auto counter reload
The counters that support the auto counter reload feature can be
enumerated in the CPUID Leaf 0x23 sub-leaf 0x2.
Add acr_cntr_mask to store the mask of counters which are reloadable.
Add acr_cause_mask to store the mask of counters which can cause reload.
Since the e-core and p-core may have different numbers of counters,
track the masks in the struct x86_hybrid_pmu as well.
