perf vendor events amd: Add Zen 4 metrics
Add metrics taken from Section 2.1.15.2 "Performance Measurement" in
the Processor Programming Reference (PPR) for AMD Family 19h Model 11h
Revision B1 processors.
The recommended metrics are sourced from Table 27 "Guidance for Common
Performance Statistics with Complex Event Selects".
The pipeline utilization metrics are sourced from Table 28 "Guidance
for Pipeline Utilization Analysis Statistics". These are new to Zen 4
processors and useful for finding performance bottlenecks by analyzing
activity at different stages of the pipeline. Metric groups have been
added for Level 1 and Level 2 analysis.
