type: handle the 0-length array case in abiSizeAdvanced
This fixes a panic in `unionAbiSize` when a 0-length array of a union is used as a struct field.
Because `resolveTypeLayout` does not resolve the `elem_ty` if `arrayLenIncludingSentinel` returns
0 for the array, the child union type is not guaranteed to have a resolved layout at this point.
Fixed this case by just returning 0 here.
