        CSSStyleSelector should provide a way to obtain rules from non-author stylesheets
        https://bugs.webkit.org/show_bug.cgi?id=61454

        Replaced bool and enum arguments of styleRulesForElement and pseudoStyleRulesForElement
        by one enum, and provided a way to obtain rules from UA/user stylesheets.

        * css/CSSRule.h: Removed CSSRuleFilter.
        * css/CSSStyleSelector.cpp:
        (WebCore::CSSStyleSelector::styleRulesForElement): See above.
        (WebCore::CSSStyleSelector::pseudoStyleRulesForElement): Ditto.
        * css/CSSStyleSelector.h: Moved CSSRuleFilter here.
        * editing/markup.cpp:
        (WebCore::styleFromMatchedRulesForElement): Calls styleRulesForElement.
        * inspector/InspectorCSSAgent.cpp:
        (WebCore::InspectorCSSAgent::getStylesForNode): Ditto.
        * page/DOMWindow.cpp:
        (WebCore::DOMWindow::getMatchedCSSRules): Ditto.
