[v2,13/23] test-qobject-output-visitor: Wean off UserDefListUnion

Commit Message

Markus Armbruster Sept. 17, 2021, 2:31 p.m. UTC

The test_visitor_out_list_union_FOO() use simple union
UserDefListUnion to cover lists of builtin types.  Rewrite as
test_visitor_out_list_struct(), using struct ArrayStruct and a lot
less code.
