perf/x86/intel: Update event constraints and cache_extra_regsfor ARL
Update perf hard-coded event constraints and cache_extra_regs[] for
Arrowlake according to the latest ARL perfmon events (V1.17).
ARL shares almost same event constraints and extra MSR configuration
with LNL except 2 differences.
- ARL P-core has different extra MSR value for OCR.DEMAND_DATA_RD.L3_MISS
and OCR.DEMAND_RFO.L3_MISS. So introduce arl_lnc_hw_cache_extra_regs[]
to reflect the difference.
- ARL-H has extra LPE cores which use crestmont architectures. Add
crestmont specific event constraints and hw_cache_extra_regs[] for LPE
cores.
