Sam Atkins 7216c6b050 LibWeb/CSS: Parse <url> as a new CSS::URL type
Our previous approach to `<url>` had a couple of issues:
- We'd complete the URL during parsing, when we should actually keep it
  as the original string until it's used.
- There's nowhere for us to store `<url-modifier>`s on a `URL::URL`.

So, `CSS::URL` is a solution to this. It holds the original URL string,
and later will also hold any modifiers. This commit parses all `<url>`s
as `CSS::URL`, but then converts it into a `URL::URL`, so no user code
is changed. These will be modified in subsequent commits.

For `@namespace`, we were never supposed to complete the URL at all, so
this makes that more correct already. However, in practice all
`@namespace`s are absolute URLs already, so this should have no
observable effects.
