This issue exists to track converting the web-component switch to use ElementInternals rather than the current FormAssociation behavior.

As part of this change, we should:

Get the DOM as clean and light as possible
Strip as much duplication of observed ARIA attributes out of the control
Ensure the control reads as expected from assistive technology
Add tests to validate the control participates in form association as expected by the platform.
