LibWeb: Implement HTML fragment serialisation and use it in innerHTML

Browse source 
The previous implementation was about a half implementation and was
tied to Element::innerHTML. This separates it and puts it into
HTMLDocumentParser, as this is in the parsing section of the spec.

This provides a near finished HTML fragment serialisation algorithm,
bar namespaces in attributes and the `is` value.
