Description
### Is your feature request related to a problem or challenge?
A thought coming off of fixing #9736 is that we could likely proactively identify issues like this by modifying sqllogictests to run multiple times with a variety of randomized configs.
### Describe the solution you'd like
Perhaps this function https://github.com/apache/arrow-datafusion/blob/6c6305159711fbca43ff7798faa52aaebcb2e7d3/datafusion/sqllogictest/src/test_context.rs#L67
could be modified to set random configs over a range of valid values.
Then this could be modified to run in a loop a set number of times based on a passed option with a default.
https://github.com/apache/arrow-datafusion/blob/6c6305159711fbca43ff7798faa52aaebcb2e7d3/datafusion/sqllogictest/bin/sqllogictests.rs#L90
### Describe alternatives you've considered
If this results in tests taking too long, the default could be 1 run, but occasionally (prior to a release perhaps) a longer test with many runs could be run.
### Additional context

Research direction
Read datafusion/sqllogictest/src/test_context.rs around the linked function, then inspect datafusion/sqllogictest/bin/sqllogictests.rs around the linked option. Determine how to generate randomized valid configurations and how the run count should be passed and defaulted. Done means sqllogictests can repeat runs with randomized configurations while retaining a default of one run.
