Support defining custom cluster roles for cluster scoped instances

Is your feature request related to a problem? Please describe.

When using a cluster scoped instance of Argo CD the operator will create a separate and hard coded set of clusterroles and clusterrolebindings. Users that want to lock down the permissions of their instances need the ability to use an alternate set of clusterroles.

As an example, the new feature in Argo CD 2.10 to auto-respect RBAC (https://argo-cd.readthedocs.io/en/stable/operator-manual/declarative-setup/#auto-respect-rbac-for-controller) enables users to remove the cluster-wide view all permissions required by a cluster scoped instance and provide a much more tailored set of permissions. However the Argo CD Operator hard codes this cluster role to define view all permissions.

Describe the solution you'd like
Enable users to specify their own roles using the environment variables CONTROLLER_CLUSTER_SCOPE_ROLE and SERVER_CLUSTER_SCOPE_ROLE

Describe alternatives you've considered
Updates to the cluster role created by the operator get overridden by the operator so it's not a suitable approach.
