css: Redo for new parser This commit is still way too big, but I couldn't make it smaller. It transitions the old CSS parser to the new parser. CSS parsing is now tokenized, everything else is probably still buggy.

cssparser: Make gsk_renderer_consume_url() return a string We don't want to return a GFile because GFile can't handle can't deal with data: urls. That makes the code a bit more complicated that doesn't deal with those URLs, but it makes the other code actually work. GtkCssImageUrl also now decodes data urls immediately instead of only at the first load. So don't use data urls if you care about performance.
