We need to change parseHTMLNonNegativeInteger to take a StringView; it’s terrible to allocate memory to do this operation!

I particularly thing it’s peculiar to make this entire function a template based on character type, which we should only do if the code is really performance-sensitive, and then allocate memory just to parse an integer!

I don’t understand why two separate parsers is the way to go here. Do we really need both?
