        Enable "MoveTo{Beginninng|End}OfDocument" commands when caret
        browsing is enabled.

        This change impacts the GTK-port only as caret browsing is a
        feature only used in that platform so far.

        Test: platform/gtk/editing/selection/caret-mode-document-begin-end.html

        * editing/EditorCommand.cpp:
        (WebCore::createCommandMap): Enable the commads when in caret browsing.
