Is your feature request related to a problem or challenge?

The https://github.com/apache/datafusion/blob/main/datafusion/sql/tests/sql_integration.rs module is over 5000 lines long which makes tests in it such as parameter handling hard to manage and work with

Describe the solution you'd like

I would like some of the tests pulled out into smaller modules

Describe alternatives you've considered

Perhaps we could move all the tests for prepare and infer into a module in https://github.com/apache/datafusion/tree/main/datafusion/sql/tests/cases

Perhaps called params.rs
