LibWeb: Basic implementation of global event handlers :^)
Document and HTMLElement now inherit from HTML::GlobalEventHandlers which allows them to support "onfoo" event handler attributes. These are assignable both via IDL attributes and content attributes. Event listeners constructed this way get a special "attribute" flag on them so we know which one to replace if you reassign them. This also allows them to coexist with EventTarget.addEventListener(). This is all a bit sloppy, but it works decently for a first cut. The Window object should also inherit GlobalEventHandlers, but since we don't generate it from IDL, I haven't taken that step here. Also this would be a lot nicer if we supported IDL mixins.
