Bug report

Bug description:

After creating a UNIX socket server with loop.create_unix_server() and then closing it using Server.close(), then the UNIX socket file is still left on disk.

Although asyncio itself can handle this on the next startup since #72585, it's still a bit rude (and confusing) to leave stale things around on the file system.

Callers can make sure to pair Server.close() with an os.unlink(). But it would be a lot neater if Python could automatically do this, as basically everyone should do it anyway.

CPython versions tested on:

3.9

Operating systems tested on:

Linux
