ArC: fix NPE in InvokerGenerator

[mkouba]

• when a primitive param is annotated with a type annotation

Unfortunately, the only workaround I can see is to avoid using primitives and use the wrapper types instead.

Fixes #50225.

That should be no issue though, right?

Well, I wouldn't call it "no issue" because whenever you use a primitive param with a type annotation on a method that is called via Invoker then you get a NPE during build and the error message is not exactly "actionable".

LGTM, although the test on several places iterates over a singleton list, which is unnecessary.

Yeah, sure. I just copied and modified one of the existing test. Feel free to jump in this PR ;-).

Done :-)
