Remove uses of type() part 2 (#38140)
Summary:
I'm mostly done with cleaning up test/ folder. There're a bunch of remaining callsites but they're "valid" in testing `type()` functionalities. We cannot remove them until it's fully deprecated.
Next PR would mainly focus on move some callsites to an internal API.
