Port tests in joins.rs to sqllogictest

[alamb]

Is your feature request related to a problem or challenge?

Part of #6195. We are trying to keep the DataFusion code base clean and easy to contribute to and modify. Part of doing so is having a single location for most test coverage so new tests can be added easily and people can follow the existing patterns easily

Describe the solution you'd like

Port the tests in https://github.com/apache/arrow-datafusion/blob/main/datafusion/core/tests/sql/joins.rs to joins.slt in https://github.com/apache/arrow-datafusion/tree/main/datafusion/core/tests/sqllogictests/test_files

This is a subtantial task -- and perhaps is done best in several smaller PRs

Notes:

1. Instructions for running sqllogitest are here: https://github.com/apache/arrow-datafusion/tree/main/datafusion/core/tests/sqllogictests
2. If you have questions or hit issues, please let me know
