        WebKit2: Merge SelectionState and TextInputState
        https://bugs.webkit.org/show_bug.cgi?id=58919

        Combined TextInputState and EditorState in one structure, which is updated whenever we get
        a chance to. There is no sense to keep possibly stale SelectionState data when we have already
        requested the most recent data synchronously.

        This also simplifies the code, as we don't need to pass the state around in a separate variable.
