rust: sync: set_once: Implement Send and Sync
Implement Send and Sync for SetOnce<T> to allow it to be used across
thread boundaries.
Send: SetOnce<T> can be transferred across threads when T: Send, as
the contained value is also transferred and will be dropped on the
destination thread.
Sync: SetOnce<T> can be shared across threads when T: Sync, as
as_ref() provides shared references &T and atomic operations ensure
proper synchronization. Since the inner T may be dropped on any
thread, we also require T: Send.
