A few versions ago we introduced compatibility with the native `form`
element. This means that behind the scenes we render hidden inputs that
are kept in sync which allows you to submit your normal form and get
data via `new FormData(event.currentTarget)`.

Before this change every form related component (Switch, RadioGroup,
Listbox and Combobox) always had to be passed a `value` and an
`onChange` regardless of this change.

This change will allow you to not even use the `value` and the
`onChange` at all and keep it completely uncontrolled.

This has some changes:

- `value` is made optional
- `onChange` is made optional (but will still be called if passed
  regardless of being controlled or uncontrolled)
- `defaultValue` got added so that you can still pre-fill your values
  with known values.
- `value` render prop got exposed so that you can still use this while
  rendering.

This should also make it completely compatible with tools like Remix
without wiring up your own state.
