Subject: fix(node): expose channels in worker_threads (#19086)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR ensures that node's `worker_threads` module exports
`MessageChannel`, `MessagePort` and the `BroadcastChannel` API. Fixing
these won't make `esbuild` work, but brings us one step closer 🎉

Fixes #19028 .
