These are the building blocks for us to automatically create an ArgGroup when deriving Args on a struct. This will make it easier to compose (write validation rules) particularly when the struct comes from a third party.

The next step will then be to support deriving Args on enums, see #2621

Since the `name` is changed to be the package name, we can't use it as
(1) its not as predictable and (2) it can lead to conflicts if a
`Parser` is flattened into a `Parser`
