Refactors Event and EventTarget so that they better encapsulate their non-public data as well as are more forward compatible with things like DOM Nodes. Moves `dom_types.ts` -> `dom_types.d.ts` which was always the intention, it was a legacy of when we used to build the types from the code and the limitations of the compiler. There was a lot of cruft in `dom_types` which shouldn't have been there, and mis-alignment to the DOM standards. This generally has been eliminated, though we still have some minor differences from the DOM (like the removal of some deprecated methods/properties). Adds `DOMException`. Strictly it shouldn't inherit from `Error`, but most browsers provide a stack trace when one is thrown, so the behaviour in Deno actually better matches the browser. `Event` still doesn't log to console like it does in the browser. I wanted to get this raised and that could be an enhancement later on (it currently doesn't either).
