Event errors on AWS

[hsane-dev]

Running perfspect metrics on r5xl:
Error: failed to put perf events into groups: unrecognized event format: "event syntax error: '{cpu/event=0x28,umask=0x07,period=200003,name=CORE_POWER..'"

These are the CORE_LICENSE_LEVEL based events to detect cycles spent in AVX, should work on metal though.

If 5th gen is not supported in AWS, it should report the same after recognizing format. this seems to be failing on unrecognized power events. If not supported, power license events could be discarded if detected instance is a cloud instance maybe?

Never mind, I realized that no PMUs are exposed in this generation unless metal. I am not even getting fixed counter events.

Could we however detect instance type and if not supported, report the same rather than starting colleciton and then failing when perf cant capture the event?
