Moves dns-horizontal-autoscaler to a separate service account
Similar to #38816.
As one of the cluster add-ons, dns-horizontal-autoscaler is now using the default service account in kube-system namespace, which is introduced by https://github.com/kubernetes/kubernetes/blob/master/cluster/addons/e2e-rbac-bindings/random-addon-grabbag.yaml for the ease of transition. This default service account will be removed in the future.
This PR subdivides dns-horizontal-autoscaler to a separate service account and setup the necessary permissions.

Note:
The new entry `"preventSinglePointFailure":true` ensures kube-dns to have at least 2 replicas when there is more than one node. Mitigate the issue mentioned in #40063.
