perf/x86/intel: Update event constraints for ICX

BugLink: https://bugs.launchpad.net/bugs/1947888
[ Upstream commit ecc2123e09f9e71ddc6c53d71e283b8ada685fe2 ]

According to the latest event list, the event encoding 0xEF is only
available on the first 4 counters. Add it into the event constraints
table.
