cluster: Add support to cluster to work with `NODE_OPTIONS="--inspect"
When using cluster and --inspect as cli argument it is correctly handled and each worker will use a different port, this was fixed by #13619. But when env var NODE_OPTIONS="--inspect" is set this logic doesn't apply and the workers will fail as they try to attach to the same port.
Fixes: https://github.com/nodejs/node/issues/19026
