Using UDS for communication in debugger

IIUC, the current debugpyClient communicates with debugpy via a TCP connection. However, due to security limitations in our use case, we are unable to use network sockets for the communication.

I understand debugpy currently only supports TCP connections, but I have proposed an issue for debugpy to accept UDS as well([link](https://github.com/microsoft/debugpy/issues/1607)). If they are onboard with this, can we update ipykernel logic to use UDS instead of TCP? Or will there be any concerns there?
