Original change's description:
> Reland "[shared-struct] Add Atomics.Condition"
>
> This is a reland of commit e2066ff6
>
> Changes since revert:
> - Rebased against c9918524, which
>   uses the external pointer table for the WaiterQueueNode stored
>   in the state field when compressing pointers. This relaxes
>   the alignment requirement of the state field to be 4-bytes when
>   compressing pointers.
> - Moved the state field into the JSSynchronizationPrimitive base
>   class, since alignment and padding can now be made simpler.
