LibWeb/CSS: Add alternative src() syntax for URLs

Browse source 
url() has some limitations because of allowing unquoted URLs as its
contents. For example, it can't use `var()`. To get around this, there's
an alternative `src()` function which behaves the same as `url()` except
that it is parsed as a regular function, which makes `var()` and friends
work properly.

There's no WPT test for this as far as I can tell, so I added our own.
