        Web Inspector: inspector settings/properties/states management
        should be extracted into separate class.

        We have a lot of flags/values in InspectorController.
        Some flags are persisting into profile.
        Others are part of inspector state for frontend.
        All these flags should keep their values after navigation.
        It'd be better to extract these flags/values into separate
        class which will care about theirs lifetime.
