- Razor rendering now understands `TagMode` which allows void elements to be rendered.
- Added a `TagStructure.WithoutEnd` bit to `InputTagHelper`, `ImageTagHelper` and `UrlResolutionTagHelper`. This will allow users to write the various elements in the void format. Used the HTML5 spec to determine the elements appropriate.
- Added tests to ensure `TagMode.StartTagOnly` is rendered properly.
- Updated a few functional tests to showcase the void element formats.
