perf/x86/intel: Update event constraints and cache_extra_regsfor ICX

Update perf hard-coded event constraints and cache_extra_regs[] for
Icelake server according to the latest ICX perfmon events (v1.30).

Since the value of cache extra registers differs with previous
generations, introduce new snc_hw_cache_extra_regs[] to represent the
value of extra registers on ICX.
