Andreas Kling 8a6a9a8fb6 LibWeb: Move DOM event dispatch to its own class
For now, the new DOM::EventDispatcher is very simple, it just iterates
over the set of listeners on an EventTarget and invokes the callbacks
as it goes.

This simplifies EventTarget subclasses since they no longer have to
implement the callback mechanism themselves.
