Fix nodes power state on Azure

[feiskyer]

What this PR does / why we need it:

#68033 implements InstanceShutdownByProviderID for azure, but it uses VM.ProvisioningState to determine if the VM is running. Which never returns true even if the VM is not running.

The provider should uses (and parse) InstanceView.Statuses array -- specifically PowerState/running status.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #68916

use one function for both azure_standard.go and azure_vmss?

	if vm.InstanceView != nil && vm.InstanceView.Statuses != nil {
 		statuses := *vm.InstanceView.Statuses
 		for _, status := range statuses {
 			state := to.String(status.Code)
 			if strings.HasPrefix(state, vmPowerStatePrefix) {
 				return strings.TrimPrefix(state, vmPowerStatePrefix), nil
 			}
 		}
 	}

Much more complicated because they are different GO struct.

It is possible that vmssVM gets removed just before this call.
