Allow update of node pool workload metadata config

[emilymye]

Release Note Template for Downstream PRs (will be copied)

container: Added update support for `node_config.workload_metadata_config` to `google_container_node_pool`

Fixes hashicorp/terraform-provider-google#4041

This field is only updatable on node pool, so we've chosen to only make it updatable on node_pool and keep it ForceNew on container cluster

In addition, because cluster.workload_identity_config and node_pool.workload_metadata_config are closely related, I decided to combine the test

We removed ForceNew from sandbox_config but the code seems to only apply to workload_metadata_config, how does that work?

[emilymye]

i for sure removed it from the wrong config when transferring over to MM
