Add accelerator_topology_mode to google_compute_resource_policy

[jamOne-]

Description

This PR adds support for the accelerator_topology_mode field in the google_compute_resource_policy resource, specifically within the workload_policy block.

This enables "Super-slicing" for TPU clusters on GKE by allowing users to set the topology mode to values such as PROVISION_ONLY or AUTO_CONNECT. The field aligns with the underlying Compute Engine API and gcloud beta compute resource-policies create workload-policy --accelerator-topology-mode capabilities.

Changes Made:

• Added acceleratorTopologyMode to mmv1/products/compute/ResourcePolicy.yaml as an Enum type.
• Updated conflict rules between accelerator_topology_mode, accelerator_topology, and max_topology_distance.
• Added a new Terraform example (resource_policy_workload_policy_accelerator_topology_mode) to auto-generate documentation.
• Added a handwritten acceptance test (TestAccComputeResourcePolicy_withTopologyMode) to verify creation and destruction.

@hao-nan-li sending a follow-up PR, because I noticed I incorrectly affected the GA provider, but the change should affect only the beta version: #16653. Sorry for that.
