Disallow cloning of file-backed Blobs. If necessary, we can enable this later but for now we disable it. The reason is because the underlying FdEntry ends up bound to the Environment/Realm under which is was created and transfering across worker threads ends up failing. Fixes: nodejs#47334

Hmm, it dose not really fix the issue, would just say that it is more "related" to it... it sure would be nice if they could be transfered too... what would it really take to solve this? Somehow making FdEntry transferable too? or |

| It fixes the crash, which is the important bit. I would recommend opening an issue to track actually making file-backed blobs transferable. |

| I think we could update it refs instead of fixes and make the original issue into a feature request then? |
