Subject: fix(ext/node): support stdin child_process IPC & fd stdout/stderr
 (#24106)

Add supports for "ipc" and fd options in child_process spawn API.

Internal changes: Adds a hidden rid and "ipc_for_internal_use" option to
Deno.Command. Used by `node:child_process`

Example:
```js
const out = fs.openSync("./logfile.txt", 'a')
const proc = spawn(process.execPath, ["./main.mjs", "child"], {
  stdio: ["ipc", out, "inherit"]
});
```

Ref #16753
