LGTM if CI is green. I guess since worker_threads are still Experimental, this can technically still land as a patch in 12.x even if it is deemed semver-major. (But I'm OK if we'd rather be cautious. Fine either way.)

Can't we just use ConstructorBehavior::kThrow for this? If there is a particular reason for throwing our own style of errors I think that's worth a comment..

@joyeecheung Yeah, it doesn’t work because that also removes the prototype property. I’m adding a comment, though.

Refactor the C++ code for creating `MessagePort`s to skip calling the constructor and instead directly instantiating the `InstanceTemplate`, and always throw an error from the `MessagePort` constructor. This aligns behaviour with the web, and creating single `MessagePort`s does not make sense anyway.

This is technically a breaking change and I’d be happy to split out the added throw into a separate PR out of caution, if anybody considers that a good idea.
