This is a reland of commit ea9a1f1cbe
Changes since revert:
- Make the state field uintptr-aligned since arm64 faults on
atomic accesses to non-naturally aligned addresses.
Original change's description:
> [shared-struct] Add Atomics.Mutex
>
> This CL adds a moving GC-safe, JS-exposed mutex behind the
> --harmony-struct flag. It uses a ParkingLot-inspired algorithm and
> each mutex manages its own waiter queue.
>
> For more details, please see the design doc: https://docs.google.com/document/d/1QHkmiTF770GKxtoP-VQ1eKF42MpedLUeqiQPfCqus0Y/edit?usp=sharing
