        Remove specialization of EventDispatcher with inversion of control.
        https://bugs.webkit.org/show_bug.cgi?id=57285

        Since some events have extra logic around their dispatch, allow them
        to dispatch themselves and specialize the logic. This change only
        converts KeyboardEvent to this model.

        No functional change, covered by existing tests.

        * dom/Event.cpp:
        (WebCore::Event::dispatch): Added.
        * dom/Event.h: Updated decls.
        * dom/EventDispatcher.cpp:
        (WebCore::EventDispatcher::dispatchEvent): Changed to ask event to dispatch
            itself.
        * dom/EventDispatcher.h: Updated decls.
        * dom/KeyboardEvent.cpp:
        (WebCore::KeyboardEvent::dispatch): Added, moving code from EventDispatcher.
        * dom/KeyboardEvent.h: Updated decls.
        * dom/Node.cpp:
        (WebCore::Node::dispatchKeyEvent): Changed to use the new ways.
