This is a reland of commit ea9a1f1c 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.

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.
