windows: add misc:initial_workspace_tracking

By default enabled, will track the initial opened workspace of a window spawned for 2 minutes or until it's moved to a different workspace.

For example: you run a launcher and open an app on workspace 1, but quickly switch to workspace 2. The app will now open on workspace 1 regardless of your switch.
