perf/x86/amd/core: Update and fix stalled-cycles-* events for Zen 2 a…
…nd later commit c7b2edd upstream. AMD processors based on Zen 2 and later microarchitectures do not support PMCx087 (instruction pipe stalls) which is used as the backing event for "stalled-cycles-frontend" and "stalled-cycles-backend". Use PMCx0A9 (cycles where micro-op queue is empty) instead to count frontend stalls and remove the entry for backend stalls since there is no direct replacement.
