LibWeb: Refactor XHR (almost) exactly to the spec

Browse source 
This makes XHR now rely on Fetch, which allows it to correct send
Origin and Referer headers, CORS-preflight and filtering and many other
goodies.

The main thing that's missing is Streams, which means we can't properly
produce progress events or switch to the Loading ready state.

This also doesn't implement the Document responseType just yet.
