Improve shutdown handling on Windows

### Description

_Originally raised in https://github.com/flowforge/flowforge-nr-launcher/pull/111#pullrequestreview-1414516901_

When running on Windows, the localfs driver issues:
```
childProcess.exec(`taskkill /pid ${projectSettings.pid} /T /F`)
```
Which essentially kills the process without ever performing a clean shutdown (so non of this code is ever executed by the launcher)

A possible future "fix" (also perhaps an improvement?) might be to utilise ipc or pipe and use process.send to tell the launcher to "shutdown" before any kill operation. This would permit a chance to verify the "shutdown" actually occurs and an opportunity to grab logs entries on the shutdown process.
