Reviewed by Ryosuke Niwa and BJ Burg.

CSSStyleSheet::cssRules() can be invoked via Web API, so it performs cross-origin check for security.
CSSStyleSheet::cssTextWithReplacementURLs() is only used for archiving style sheet now (initiated by client), so we
should skip cross-origin check to ensure content is correctly preserved. This patch adds allCSSRules() for that.

API Test: WebArchive.SaveResourcesCrossOriginLink
