perf/x86/intel: Support new data source for Lunar Lake

A new PEBS data source format is introduced for the p-core of Lunar
Lake. The data source field is extended to 8 bits with new encodings.

A new layout is introduced into the union intel_x86_pebs_dse.
Introduce the lnl_latency_data() to parse the new format.
Enlarge the pebs_data_source[] accordingly to include new encodings.

Only the mem load and the mem store events can generate the data source.
Introduce INTEL_HYBRID_LDLAT_CONSTRAINT and
INTEL_HYBRID_STLAT_CONSTRAINT to mark them.

Add two new bits for the new cache-related data src, L2_MHB and MSC.
The L2_MHB is short for L2 Miss Handling Buffer, which is similar to
LFB (Line Fill Buffer), but to track the L2 Cache misses.
The MSC stands for the memory-side cache.
