[PATCH 10/12] perf/x86/intel: Add precise OMR event support for DMR/NVL

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

The latest perfmon event database introduces below precise OMR event
support for DMR/NVL:
- MEM_LOAD_L2_MISS_RETIRED.* (event 0xd6)
- MEM_STORE_L2_MISS_RETIRED.* (event 0x4f)

These events use the same OMR MSRs as the existing OMR events, but
they are not listed in intel_pnc_extra_regs[]. As a result, perf
cannot assign the required OMR extra registers when scheduling them.

Add the new precise OMR events to intel_pnc_extra_regs[] so they can
be scheduled with the correct OMR MSRs. MEM_LOAD_L2_MISS_RETIRED.*
remains limited to GP counters 0-3, while
MEM_STORE_L2_MISS_RETIRED.* is available on all GP counters.
