        Web Inspector: InspectorRuntimeAgent should not depend on Page
        https://bugs.webkit.org/show_bug.cgi?id=57759

        Descendants of InspectorRuntimeAgent should implement a method providing access to the default
        inspected state used for console evaluations.

        * inspector/InspectorAgent.cpp:
        (WebCore::InspectorAgent::InspectorAgent): runtime agent is created and deleted along with other agents.
