perf/x86/intel: Fix DKT PEBS load/store direction for latency events, to fix sample classification

Same bug exists on Darkmont as on Gracemont:
intel_dkt_pebs_event_constraints[] applies LAT_CONSTRAINT constraints to
MEM_UOPS_RETIRED.{LOAD,STORE}_LATENCY, but does not set explicit
LOAD/STORE flags for those events.

The PEBS latency path (pebs_latency_data(), via cmt_latency_data) uses
the event flags to determine memory operation direction. Without an
explicit STORE flag, samples from MEM_UOPS_RETIRED.STORE_LATENCY can be
misclassified as LOADs.

Set explicit LOAD/STORE flags in intel_dkt_pebs_event_constraints[] for:

- MEM_UOPS_RETIRED.LOAD_LATENCY
- MEM_UOPS_RETIRED.STORE_LATENCY

This fixes incorrect STORE sample classification. Additionally remove
INTEL_HYBRID_LAT_CONSTRAINT() since no one uses it anymore.
