perf/x86/intel: Add core PMU support for DMR

This patch enables core PMU features for Diamond Rapids (Panther Cove
microarchitecture), including Panther Cove specific counter and PEBS
constraints, a new cache events ID table, and the model-specific OMR
events extra registers table.

For detailed information about counter constraints, please refer to
section 16.3 "COUNTER RESTRICTIONS" in the ISE documentation.
