fix(ext/node): support HTTP over Windows named pipes in node:http (#32414)
Add Windows Named Pipe support to Deno's Node.js HTTP compatibility
layer, enabling libraries like `dockerode`/`docker-modem` that use
`http.request({socketPath: "//./pipe/docker_engine"})` to work on
Windows.
Add `WindowsPipe` variant to `NetworkStream` with proper handling across
HTTP server, request properties, and Node HTTP client ops.
Implement EBUSY (ERROR_PIPE_BUSY / os error 231) retry logic in
`Pipe.connect()` for Windows, emulating libuv's `WaitNamedPipeW`
behavior with polling retries.
