        Refactoring: Extract TextCheckerClient from EditorClient
        https://bugs.webkit.org/show_bug.cgi?id=53213

        Created new abstract class TextCheckerClient. The class has
        spellcheck related API which is split.
        This is the first step for sharing spell-checking codebase
        between ports. A standalone TextCheckerClient implementation
        should be done in future changes.

        No new tests. No behavioral change.
