cluster: fix port reuse between cluster

[islandryu]

Fixes: #60086

If the message.index passed to queryServer becomes out of sync due to errors or other issues, it may prevent a cluster from reusing a port that was acquired by another cluster.
To address this, I modified the code so that the handle key no longer includes the index (except when the port number is 0), and only the latest handle corresponding to a successfully acquired port is stored.

@islandryu - Thank you for proposing this change, the underlying issue is causing trouble for us with TCP, UDP, and HTTP servers: #60086. Any chance of getting this merged anytime in the near future?

We’ll need to get this reviewed before it can move forward.

@nodejs/cluster
would anyone be able to take a look?
