[lua] Improve codegen for handling instance Var functions

[Frixuu]

This PR changes how class instance fields are handled, improving interop with Lua APIs.

• Var fields that are functions should now behave as "dot methods"
• assignments to "dot methods" should no longer change their signatures
• passing as parameters and returning of "dot methods" should no longer wrap them in helper functions
• non-function members should be left as-is
• static methods should be left as-is
• instance methods should be left as-is
• anonymous structures' fields should be left as-is

Fixes #10799

Thank you for the contribution! I don't know anything about the Lua target, but this looks quite correct.

Please note that the Lua tests have been disabled since 8027d74 and 3e34d27. I think there was some kind of setup issue which was unresolved, and nobody bothered to fix it. I'm fine with merging this regardless, but it would be good to have this addressed either way so that we can be sure we're not breaking anything with changes like this.

I will also like to see this merged. What is preventing it?

[Simn]

I'll merge it even without the tests running. If something breaks, we'll know who to blame!

The original surhor or the one who merged it. Never blame the middle man 😎 El mar., 3 ene. 2023 5:33, Simon Krajewski ***@***.***> escribió:
