perf vendor events amd: Add Zen 4 uncore events 



Add uncore events taken from Section 2.1.15.5 "L3 Cache Performance
Monitor Counter"s and Section 7.1 "Fabric Performance Monitor Counter
(PMC) Events" in the Processor Programming Reference (PPR) for AMD
Family 19h Model 11h Revision B1 processors. This constitutes events
which capture L3 cache activity and data bandwidth for various links
and interfaces in the Data Fabric.
