feat(azure): pass HYPERSHIFT_IMAGE for self-managed clusters only

Add conditional logic to pass HYPERSHIFT_IMAGE environment variable
to Azure Disk and Azure File CSI driver operators only when running
on self-managed Azure HyperShift clusters.

For ARO HCP deployments, the Secret Provider Class pattern is used
instead of token-minter, so HYPERSHIFT_IMAGE is not needed. This
change detects ARO HCP mode by checking for the presence of
ARO_HCP_SECRET_PROVIDER_CLASS_FOR_* environment variables.
