feat(unstable): add windowsRawArguments to SpawnOptions (#16319)

This change adds `windowsRawArguments` to `SpawnOptions`. The option enables
skipping the default quoting and escaping while creating the command on
windows.

The option works in a similar way as `windowsVerbatimArguments` in
child_process.spawn options in Node.js, and is necessary for simulating
it in `std/node`.

closes #8852
