✨ Update form component

[kschiffer]

Summary

This PR applies some updates to the form component that are needed to make better use of formik and enable better internal form middlewares.

Changes

• Refactor all form related components to functional components, using hooks
• Make better use of Formiks API to simplify the component
  • This made it possible to get rid of <InnerForm /> within <Form />, making the component a lot more concise
• Use Formik in a more idiomatic way

Testing

Manual and existing e2e.

Regressions

The end-to-end tests should catch critical bugs. Since the <Form />-component is so ingrained into the Console, it is not unlikely that this change results in bugs. I'm doing my best to test to prevent that.

Notes for Reviewers

• Doing this also to enable some assistant functions that will come in handy when implementing End device onboarding flow #4847, such as automatic stripping of values for disabled fields.
