Add context to table UDFs

[wmTJc9IK0Q]

This adds a new BindArgumentsContext field to the tableFunction struct to allow table UDFs to retrieve values from the query context.

This was easier to make as a non-breaking change unlike the previous #53 and doesn't change the ability to use this context during the Fill* funcs if necessary.

Pull Request Overview

This PR adds context support to table UDFs by introducing a new BindArgumentsContext field to the tableFunction struct. This allows table UDFs to retrieve values from the query context, similar to how scalar UDFs already have this capability.

• Adds BindArgumentsContext field to tableFunction struct for context-aware binding
• Updates wrapper functions to handle both BindArguments and BindArgumentsContext
• Modifies bind logic to prioritize BindArgumentsContext when available, falling back to BindArguments
• Introduces tableFuncContext struct to pass context store to bind functions

Out of curiosity - is the copilot review something you enabled in your settings? I.e., I can't seem to find anything related to that on the repository level and AFAIK I did not enable it. 🤔

Yes, it's the private copilot, I also have it.

[wmTJc9IK0Q]

Didn't realize it would trigger on other people's repos, that's interesting. But yes, I have a subscription so that's why it got triggered.

Any feedback on this version of the change? I think it's pretty straightforward and in line with the scalar UDF one

[taniabogatsch]

Code looks good - could you have a look at the failing tests?

[VGSML]

@wmTJc9IK0Q Looks really good!

[wmTJc9IK0Q]

@taniabogatsch Fixed. Thanks.
