We now don't absolutize the URL during parsing, keeping it as a CSS::URL object which we then pass to the "fetch an external image for a stylesheet" algorithm. Our version of this algorithm is a bit ad-hoc, in order to make use of SharedResourceRequest. To try and reduce duplication, I've pulled all of fetch_a_style_resource() into a static function, apart from the "actually do the fetch" step.
