JSPromise<T extends JSAny?> extension type

A JavaScript Promise or a promise-like object.

Because JSPromise is an extension type, T is only a static guarantee and the JSPromise may not actually resolve to a T.

Also like with JSArray, T may introduce additional checking elsewhere. When converted to a Future<T>, there is a cast to ensure that the Future actually resolves to a T to ensure soundness.
