[PATCH 04/12] perf/x86/intel: Update arw_latency_data() mem-op direction handling

[Dapeng Mi <dapeng1.mi@linux.intel.com>]

Align arw_latency_data() with other *_latency_data() helpers by
explicitly decoding LOAD/STORE event flags when setting the sampled
memory operation direction.

This keeps the latency data path behavior consistent across platforms
and avoids relying on implicit direction inference.
