Support to get PromiseIsHandled internal slot in Promise When trying to implement unhandled rejection in servo/servo#20755, I'd need to check the internal slot of Promise which is the step 4.1.1 for the spec of [notify about rejected promises](https://html.spec.whatwg.org/multipage/webappapis.html#notify-about-rejected-promises). So, this PR will add the API to add the `GetPromiseIsHandled` method. <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/mozjs/150) <!-- Reviewable:end -->
