        [Refactoring] Auto correction panel should be handled by its own class.
        https://bugs.webkit.org/show_bug.cgi?id=55571

        Extracted code inside SUPPORT_AUTOCORRECTION_PANEL into
        SpellingCorrectionController class.
        This change also remove some SUPPORT_AUTOCORRECTION_PANEL guard if
        code paths inside the never reached without autocorrection support.
        Removing guards reduces unintentional build breakage.

        No new tests, no behavior chagne.
