feat: Add named pipes entrypoint for Visual Studio

[EricCornelson]

Adding an entrypoint for external users (e.g. Visual Studio) which uses named pipes instead of TCP sockets.

Can we handle this in the existing vsDebugServer? E.g. it already can be run as node debug-server.js <port-number>, maybe if the port number is not numeric/is an absolute path we treat it as a socket/pipe.

Closing as part of our housekeeping, if you still need this let me know or reopen it
