chore(sql-udf): update test cases for implicit type cast support

[xzhseh]

I hereby agree to the terms of the RisingWave Labs, Inc. Contributor License Agreement.

What's changed and what's your intention?

As titled, since implicit type cast for udf has been supported in #14338.

P.S. Create function will be much slower (~4x) after supporting implicit type cast, but it's alright.

Checklist

• I have written necessary rustdoc comments
• I have added necessary unit tests and integration tests
• I have added test labels as necessary. See details.
• I have added fuzzing tests or opened an issue to track them. (Optional, recommended for new SQL features Sqlsmith: Sql feature generation #7934).
• My PR contains breaking changes. (If it deprecates some features, please create a tracking issue to remove them in the future).
• All checks passed in ./risedev check (or alias, ./risedev c)
• My PR changes performance-critical code. (Please run macro/micro-benchmarks and show the results.)

• My PR contains critical fixes that are necessary to be merged into the latest release. (Please check out the details)

Documentation

• My PR needs documentation updates. (Please use the Release note section below to summarize the impact on users)

Release note

The previous docs for sql udf in #14139 needs to be updated, specifically we don't need to explicit cast multiple types when calling sql udf.

How did you measure that?

How did you measure that?

Previously the overall test cases will finished in ~1500 ms, currently ~6000ms.
And after manually reviewing the implementation in #14338 & testing, it seems that the delay is mainly due to create function.
Anyways I think this is worth and acceptable. 😄
