net: throw on multiple listen calls

[mcollina]

Fixes #53204

Server.listen() could accept a second listen call while the first listen was still pending, allowing the later request to replace the earlier one. Track pending listen state and throw ERR_SERVER_ALREADY_LISTEN consistently.

The state is cleared on close, listen errors, handle transfer, and pipe permission failures.
