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).
1. Array elements are now grouped the same as in Node.js
2. Limit to 100 (Node.js default) elements to display in iterable
3. Print each element in new line if excessing max line length (same as in Node.js)
4. Print length of the TypedArray
5. Print information about empty items in Array
