perf vendor events amd: Add Zen 6 metrics
Add metrics taken from Section 1.2 "Performance Measurement" of the
Performance Monitor Counters for AMD Family 1Ah Model 50h-57h Processors
document available at the link below.
The recommended metrics are sourced from Table 1 "Guidance for Common
Performance Statistics with Complex Event Selects".
The pipeline utilization metrics are sourced from Table 2 "Guidance
for Pipeline Utilization Analysis Statistics". These are useful for
finding performance bottlenecks by analyzing activity at different
stages of the pipeline. There are metric groups available for Level 1
and Level 2 analysis.
