Re: [w3c/webcomponents] Need callback for form submit data (#187)

@tkent-google There is no `clearFormValue` analogous to `setFormValue` in element internals. This means once we have set this form value, something will be sent to the server. This prevents implementation of a checkbox like control(I am trying to implement a toggle switch) where when the checkbox is checked the data is sent, but if it is unchecked, nothing is sent to the server.
