codegen: Fix nullable array in function params

Fixes #1133

Take over of #1136 except it only generates Option if it is not a return type. To avoid generating Option<Vec<T>>

Ok seems like gir doesn't give us a way to know if the array is zero-terminated or not...that makes it more difficult

To avoid generating Option<Vec>

Why? That seems like the correct thing to do, even if it's inconvenient.

It's an attribute in the XML though.

I know, but it is not parsed nor passed around...

Uh... what?! 🤣

We assume always that it's zero-terminated unless there is an array length?

Any chance of getting forward on this? This prevents certain features from being used at all.

(For example: user scripts & stylesheets in the webkit6 crate. I needed to make local changes to the generated code in order to use those.)
