LibWeb/HTML: Implement report_validity

This implements the previously stubbed out `report_validity` method. The specification is not very clear on how to exactly report the validity. For now, we bring the first visible invalid control into view and focus it. In the future, however, it would make sense to support more complex scenarios and be more aligned with the other implementations.
