perf/x86/intel: Update event constraints for PTL

Browse source

Update perf hard-coded event constraints for Pantherlake according to
the latest PTL perfmon events (V1.05).

PTL has almost same perf event list as LNL except some PEBS event
constraints of E-core (exactly same on P-core). Define
intel_dkt_pebs_event_constraints[] to reflect the PTL E-core specific
PEBS event constraints.
