Set Paused condition to align with new CAPI recommendation

[nojnhuh]

/kind feature

Describe the solution you'd like

Fulfill CAPI's new recommendation that providers set a Paused condition on resources as described by kubernetes-sigs/cluster-api#10519.

Anything else you would like to add:

Ensure that a Paused: false condition doesn't factor into the general assumption that all conditions must be true in order for Ready to become true.

Environment:

• cluster-api-provider-azure version:
• Kubernetes version: (use kubectl version):
• OS (e.g. from /etc/os-release):
