Cherry pick of #9016 on release-v3.28.

#9016: Fix non-HPC Calico for Windows issues

Original PR Body below

The windows upgrade code was cleaned up in #7857, but there were leftover calls to it in node-service.ps1, leading to errors:

flag provided but not defined: -should-install-windows-upgrade

In addition to that, the token refresher, when run in a non-HPC scenario, would fail (on top of being unnecessary in non-HPC since that already requires the kubeconfig to be copied into the windows host):

2024-07-16 20:38:31.133 [FATAL][5064] cni-config-monitor/token_watch.go 59: Failed to read service account namespace file error=open /var/run/secrets/kubernetes.io/serviceaccount/namespace: The system cannot find the path specified.

These were masked by the fact that logs are complex to get in non-HPC windows (requires RDP access into the host machine, so e2e failures retrieve nothing), and kubectl get nodes would show the windows nodes as 'Ready' even though these errors were occurring.
