The Extended PEBS feature, introduced in the Goldmont Plus microarchitecture, supports all events as "Extended PEBS". Introduce flag PMU_FL_PEBS_ALL to indicate the platforms which support extended PEBS. To support all events, it needs to support all constraints for PEBS. To avoid duplicating all the constraints in the PEBS table, making the PEBS code search the normal constraints too.
