Allow setting both enable_autopilot and workload_identity_config in google_container_cluster resource

[AshZhang]

This PR enables the creation of GKE clusters with both Autopilot and WorkloadALTS enabled (both enable_autopilot and workload_alts_config block set).

The workloadALTSConfig JSON field in the GKE cluster REST resource requires the workloadIdentityConfig field to be present as well, so the workload_alts_config block requires the workload_identity_config block to be present. This PR removes the ConflictsWith constraint between enable_autopilot and workload_identity_config so that a non-empty workload_identity_config block can be specified to satisfy the REST API to create the cluster.

container: allowed both `enable_autopilot` and `workload_identity_config` to be set in `google_container_cluster` resource.

LGTM, only a small nitpick
