[benchmark] Disable some new Set tests with overlong runtime

[palimondo]

PRs #23690 and #24156 have improved the performance coverage of Set type. The workloads in #24156 have been tune in with #21300 in mind. This means that some larger multipliers were selected assuming the presence of optimizations from #23100. This PR temporarily disables following test where it currently results in runtimes over 30 ms (these are guaranteed to include a context switch and are therefore more susceptible to be noisy and case false performance change):

• Set.isStrictSubset.Int100
• Set.isStrictSubset.Seq.Empty.Int
• Set.isStrictSuperset.Seq.Int.Empty

How to read the data

The tables contain differences in performance which are larger than 8% and differences in code size which are larger than 1%.

If you see any unexpected regressions, you should consider fixing the
regressions before you merge the PR.

Noise: Sometimes the performance results (not code size!) contain false
alarms. Unexpected regressions which are marked with '(?)' are probably noise.
If you see regressions which you cannot explain you can try to run the
benchmarks again. If regressions still show up, please consult with the
performance team (@eeckstein).
