## Which issue does this PR close? <!-- We generally require a GitHub issue to be filed for all bug fixes and enhancements and this helps us generate change logs for our releases. You can link an issue to this PR using the GitHub syntax. For example `Closes #123` indicates that this PR will close issue #123. --> Try to implement the idea in https://github.com/apache/datafusion/issues/12415 for a single `substr` function ## Rationale for this change See https://github.com/apache/datafusion/issues/12415 <!-- Why are you proposing this change? If this is already explained clearly in the issue then this section is not needed. Explaining clearly why changes are proposed helps reviewers understand your changes and offer better suggestions for fixes. --> ## What changes are included in this PR? Organize `sqllogictest`s for a single string function into different files (see `substr_runner.slt` for the idea) Then we can set up logically equivalent table with different physical string column type (String/StringView), and repeat tests defined in another file One decision to make is whether to keep similar tests in one file, or one folder per function under test Generally different function require different kinds of data in table to test, and also they might have different number of string columns, so I think it's cleaner to separate functions to different files (but similar function like ltrim/rtim can be kept in single file) <!-- There is no need to duplicate the description in the issue here but it is sometimes worth providing a summary of the individual changes in this PR. --> ## Are these changes tested? <!-- We typically require tests for all PRs in order to: 1. Prevent the code from being accidentally broken by subsequent changes 2. Serve as another way to document the expected behavior of the code If tests are not included in your PR, please explain why (for example, are they covered by existing tests)? --> ## Are there any user-facing changes? <!-- If there are user-facing changes then we may require documentation to be updated before approving the PR. --> <!-- If there are any breaking changes to public APIs, please add the `api change` label. --> -- This is an automated message from the Apache Git Service.
