html: Add tests for SubmitEvent interface

Specification PR: whatwg/html#4984

These look great, ideally we also have a manual test (maybe they can be automated now) where we hit enter inside a text input which causes the browser to select the submitter.

A way to trigger implicit submission is not standardized. https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#implicit-submission

I remember we had a discussion about how to handle tests for such de-facto behavior in WPT, but I don't remember the result.

I guess we can add a manual test for now? Both scenarios of having a submit button and not having one are interesting, as in the latter case the submitter would be the form element which I'm not sure is what we want to expose through this API?

My memory is that we put them in separate files with a suffix like .optional and a HTML comment explaining how it is testing a common or "should" behavior, but that failures can be OK because it is not testing a fully-standardized behavior.

https://web-platform-tests.org/writing-tests/file-names.html .optional for SHOULD-type behaviour, .tentative for not yet specced behaviour.

Thanks! I added implicit-submission.optional.html.
