Implement all currently supported flavors of Azure authentication for ASO

[nojnhuh]

CAPZ supports several different mechanisms for authenticating to the Azure API as documented at https://capz.sigs.k8s.io/topics/multitenancy.html. ASO supports the same options (AFAICT) as described here: https://azure.github.io/azure-service-operator/guide/authentication/.

Whichever option a user chooses to authenticate with CAPZ, that should be passed through to be used for ASO.

Some more context is described in the ASO proposal: https://github.com/kubernetes-sigs/cluster-api-provider-azure/blob/main/docs/proposals/20230123-azure-service-operator.md#security-model
