perf vendor events amd: Add Zen 5 data fabric metrics

Add data fabric metrics taken from Section 2.1.16.2 "Performance
Measurement" in the Processor Programming Reference (PPR) for AMD Family
1Ah Model 02h Revision C1 Processors document available at the link

The recommended metrics are sourced from Table 28 "Guidance for Common
Performance Statistics with Complex Event Selects". They capture data
bandwidth for various links and interfaces in the data fabric.
