        Add support for registering noAccess URL schemes:
        1-  Add FrameLoader::registerURLSchemeAsNoAccess, and have SecurityOrigin check
        that list upon construction (similar to how isLocal is implemented).
        2-  Make InspectorController call grantUniversalAccess on its Document's
        SecurityOrigin at the time when windowScriptObjectAvailable is called.

        This enables content such as the inspector to be loaded from a custom (non-file)
        URL, which is how Chromium loads the inspector.  It also allows other URL schemes
        to be treated like data: URLs, which Chromium utilizes for its various HTML-based
        UI panels.
