feat(arm): AKSEncryptionAtHostEnabled

Description

We converted the check 'AKSEncryptionAtHostEnabled' from TERRAFORM language to the ARM language so that it also works on resources that are defined in the ARM language.

Fixes # (issue)

Description

Ensure that the AKS cluster encrypt temp disks, caches, and data flows between Compute and Storage resources

Fix

To fix the issue, ensure that the 'enableEncryptionAtHost' property is set to true for both Microsoft.ContainerService/managedClusters and Microsoft.ContainerService/managedClusters/agentPools resources. This enables encryption at host for the VM host of AKS agent nodes, ensuring data stored on the VM host is encrypted at rest and flows encrypted to the Storage service.
