Luke Wilde 344785ae3a LibWeb: Implement the EventTarget constructor
This is typically used as `class A extends EventTarget`. It's usage can
be found on websites such as https://loadout.tf/

This has the quirk that we don't do set the EventTarget prototype for
HTML::Window, as it would cause a null deref on startup. However, given
it wasn't doing this before, I don't think it should cause any issues.
