`getCalleeFunctionType` seems to be able to work with a `callee_type` set to null (there is an if else specifically for this as far as I can see). It essentially takes the function arguments and results to build the correct type for a non-variadic function. However, I think the question is not relevant for this revision and it does not hurt to set the `callee_type` either.
