Log Message:
-----------
Align with disallowing <url> type in attr()
https://bugs.webkit.org/show_bug.cgi?id=314833
rdar://problem/177540489
Reviewed by Anne van Kesteren.
Disallow <url> in attr() per
https://github.com/w3c/csswg-drafts/issues/5079#issuecomment-3329306728
Also fix handling of unknown unit types: an <attr-unit> that does not
match a known CSS unit should trigger fallback rather than failing the
substitution outright.
Spec: https://drafts.csswg.org/css-values-5/#attr-notation
