Add state upgrader to DCL resource google_dataproc_workflow_template

[zli82016]

1. Added the state upgrader override to DCL resources.
2. Backfilled the field terraform_labels with state upgrader for resource google_dataproc_workflow_template. gke_cluster_config and metastore_config are beta only fields.

Tested the provider upgrade locally from 4.84 and 5.5 respectively.

dataproc: backfilled the field `terraform_labels` for resource `google_dataproc_workflow_template`, so the resource recreation will not happen during the provider upgrade from `4.x` to `5.7`

Some fields are not in GA, so there could be two options to add the state upgrader migration files for the DCL resources to handle the version issue.

1. Add the migration file with version guard to the handwritten folder mmv1/third_party/terrform/services/XXXX.
2. Add the version specific migration file to the new folders tpgtools/ga/services/XXXX and tpgtools/beta/services/XXXX.

I chose the first option, as I think it will make the migration to MMv1 resources easier.

tpgtool changes and generated output looks good to me
