Revert of DevTools: matched styles respect :visited/:link pseudo classes (https://codereview.chromium.org/228673002/)

Reason for revert:
Regressed host rules: crbug.com/363468

Original issue's description:
> DevTools: matched styles respect :visited/:link pseudo classes
> 
> Method StyleResolver::pseudoCSSRulesForElement is used from both WebPlatform
> (via window.getMatchedCSSRules) and inspector in its styles sidebar pane.
> Due to security reasons, this method "lies" about css rules applied for
> visited and unvisited links so that it is impossible to sniff user history.
> 
> This patch makes inspector to adjust method results so that it knows which
> rules are actually applied and which are not.
>
