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. Like with JSArray, we
only check that this is a JSPromiseRepType.
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.
