perf vendor events intel: Update tsx_cycles_per_elision metrics
Update tsx_cycles_per_elision as per:
https://github.com/intel/perfmon/pull/116
Prefer the el-start event rather than cycles-t for detecting whether
the metric will work as HLE may be disabled. Remove the metric from
sapphirerapids that has no el-start event.
