Normalize form capabilities

[scothis]

Describe the problem/challenge you have

The form component is used by the modal and summary components to render forms. The stepper component has its own form renderer that adds support for things like placeholders and validation.

Describe the solution you'd like

There should be a single system for defining forms so that experience can port between modals, summaries and steppers.

Environment:

• Octant version (use octant version): 0.16.1

I am working on this one

Currently we have forms embedded across many different components. For example the Modal, Stepper, and Cards all have form elements, but don't use a unified FormComponent.

Investigate what it would take to create a standard FormComponent and then use that component in the various places we want to render forms.

Created #2223 to track the creation of the form component which will then be used to normalize the behavior.
