feat(frontend): Cosd function

[CAJan93]

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

What's changed and what's your intention?

Implement the Cost function. This implementation is slightly different from the PSQL implementation. I do not return an error on COSD(Inf), but instead return NaN.

• Tracking Issue
• PSQL implementation

Checklist For Contributors

• I have written necessary rustdoc comments
• I have added necessary unit tests and integration tests
• I have added fuzzing tests or opened an issue to track them. (Optional, recommended for new SQL features Sqlsmith: Sql feature generation #7934).
• I have demonstrated that backward compatibility is not broken by breaking changes and created issues to track deprecated features to be removed in the future. (Please refer to the issue)
• All checks passed in ./risedev check (or alias, ./risedev c)

Checklist For Reviewers

• I have requested macro/micro-benchmarks as this PR can affect performance substantially, and the results are shown.

Thank you for the approval. I uncommented the float8.sql tests, which are about cosd. Let's see if it still passes
