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

Update perf hard-coded event constraints and cache_extra_regs[] for
Clearwater Forest according to the latest CWF perfmon events (V1.02).

An important difference is that CWF introduce new extra register values
for the L3 cache OCR events, so define darkmont specific
dkt_hw_cache_extra_regs[] array.
