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
   c87a310 ("perf/x86: Support Retire Latency"))

 - The event list, which will be supported in the perf tool later.
