Rebased version of #4399 that addresses points 2 & 5 from https://critic.hoppipolla.co.uk/showcomment?chain=9848 . Introduction of an AutoJSAPI equivalent and setting the error reporter to null will come later, as they are much larger changes and we're currently blocking any further updates to rust-mozjs that are unrelated to error reporting.

We do not intend to implement the DOM in JS, so this code isn't necessary.

This is a start towards fixing #3868. Not all callers have been fixed yet, so the `Deref` implementation remains for now.

This method is deprecated in rust master; removing its users in advance will
make a future rust upgrade smoother.

Now that we use `JSTraceable` (defined in `script`), we can create arbitrary implementations on non-`script` types (eg `Url` or `RequestHeaderCollection`) where in the past we had to rely on `Traceable` and `Untraceable` to achieve cross-crate impls of `Encodable`.
This removes the two completely. They can be reintroduced if required, though the `untraceable!` macro should suffice.
Fixes#3469
