[benchmark] Change selection of non-skipped ParseInt benchmarks

[PatrickPijnappel]

An update to #29988 in which benchmarks are selected as the representative 5. The new list is now:

• Small signed decimal
• UInt64 decimal
• UInt64 hex
• Small unsigned binary
• Small signed uncommon radix

The original PR (inadvertently) had two large hex tests and no large decimal test as primary.

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).
