Luke 19731fc14c LibWeb: Use HTML-uppercased qualified name for the Element node name
For regular elements, this is just the qualified name.
However, for HTML elements in HTML documents, it is the qualified name
uppercased.

This is used by jQuery to determine the document is an HTML document.
Not having this made jQuery assume the document was XML, causing
weird behaviour.

To do this, an internal string of qualified name is created.
This is to prevent constantly regenerating it. This is allowed by
the spec.

This is the same for the HTML-uppercased qualified name.
