LibWeb: Bring browsing context creation closer to spec

Browse source 
This patch implements the "create a new browsing context" function from
the HTML spec and replaces our existing logic with it.

The big difference is that browsing contexts now initially navigate to
"about:blank" instead of starting out in a strange "empty" state.
This makes it possible for websites to create a new iframe and start
scripting inside it right away, without having to load an URL into it.
