/**
 * QuickJSDeferredPromise wraps a QuickJS promise [[handle]] and allows
 * [[resolve]]ing or [[reject]]ing that promise. Use it to bridge asynchronous
 * code on the host to APIs inside a QuickJSContext.
 *
 * Managing the lifetime of promises is tricky. There are three
 * [[QuickJSHandle]]s inside of each deferred promise object: (1) the promise
 * itself, (2) the `resolve` callback, and (3) the `reject` callback.
 *
 * - If the promise will be fulfilled before the end of it's [[owner]]'s lifetime,
 *   the only cleanup necessary is `deferred.handle.dispose()`, because
 *   calling [[resolve]] or [[reject]] will dispose of both callbacks automatically.
 *
 * - As the return value of a [[VmFunctionImplementation]], return [[handle]],
 *   and ensure that either [[resolve]] or [[reject]] will be called. No other
 *   clean-up is necessary.
 *
 * - In other cases, call [[dispose]], which will dispose [[handle]] as well as the
 *   QuickJS handles that back [[resolve]] and [[reject]]. For this object,
 *   [[dispose]] is idempotent.
