perf/x86/intel: Add Granite Rapids
From core PMU's perspective, Granite Rapids is similar to the Sapphire
Rapids. The key differences include:
- Doesn't need the AUX event workaround for the mem load event.
(Implement in this patch).
- Support Retire Latency (Has been implemented in the commit
c87a31093c
("perf/x86: Support Retire Latency"))
- The event list, which will be supported in the perf tool later.
