deps: cherry-pick 907d7bc from upstream V8

Original commit message:

    [promise] Implement Swallowed Rejection Hook.

    This extends the current Promise Rejection Hook with two new events

      kPromiseRejectAfterResolved
      kPromiseResolveAfterResolved

    which are used to detect (and signal) misuse of the Promise constructor.
    Specifically the common bug like

      new Promise((res, rej) => {
        res(1);
        throw new Error("something")
      });

    where the error is silently swallowed by the Promise constructor without
    the user ever noticing can be caught via this hook.
