Uncore events show "event syntax error" in ‘perf stat’ output on several recent Intel Xeon Scalable and Xeon W processors

Issue

• Uncore events produce an "event syntax error" in the output of the perf stat command on Intel Xeon Cascade Lake, Ice Lake, Sapphire Rapids, Emerald Rapids, and Granite Rapids processors.
• Uncore events in Red Hat Enterprise Linux (RHEL) measure the functions of a processor that are outside of a process core but within the CPU package.
• This issue is seen when running the profiler_hardware_uncore test (part of the redhat-certification-hardware certification suite) on any system with CPU(s) from these processor families.
