[PATCH 07/11] perf/x86/intel: Update event constraints and cache_extra_regs[] for ARL

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

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.

ARL perfmon events:

https://github.com/intel/perfmon/blob/main/ARL/events/arrowlake_skymont_core.json
