@kateinoigakukun
Add JSObject.transfer and JSObject.receive APIs
28d5ec0 
These APIs allow transferring a `JSObject` between worker threads. The
`JSObject.transfer` method creates a `JSObject.Transferring` instance
that is `Sendable` and can be sent to another worker thread. The
`JSObject.receive` method requests the object from the source worker
thread and postMessage it to the destination worker thread.
