LibWeb: Start implementing "create and initialize a Document" from HTML

Browse source 
The way we've been creating DOM::Document has been pretty far from what
the spec tells us to do, and this is a first big step towards getting us
closer to spec.

The new Document::create_and_initialize() is called by FrameLoader after
loading a "text/html" resource.

We create the JS Realm and the Window object when creating the Document
(previously, we'd do it on first access to Document::interpreter().)

The realm execution context is owned by the Environment Settings Object.
