The CSS `fetch_foo()` functions resolve the URL relative to the CSSStyleSheet if one is provided. So, style values that do so need to know what CSSStyleSheet they are part of so that, for example, `url (foo.png)` is loaded relative to the style sheet's URL instead of the document's one. That all works without this change because we currently absolutize URLs during parsing, but we're in the process of stopping that. This commit adds the infrastructure for telling style values what their CSSStyleSheet is.
