Authenticates the request identity with a Databricks OAuth service principal (Authorization header) and passes a Google Cloud access token through the X-Databricks-GCP-SA-Access-Token header, so GCP account-level provisioning APIs (e.g. workspace / VPC-endpoint / customer-managed-key creation) can be called with a Databricks-governed identity when SSO is enabled and Google ID token auth is disabled. Reuses the existing serviceToServiceVisitor: the Databricks OAuth token (extracted into databricksOAuthTokenSource) is the primary, and a Google cloud-platform access token (from google_credentials or google_service_account) is the secondary. Selected explicitly via AuthType "oauth-m2m-gcp", since it combines the oauth and google credential groups that the single-auth-method check otherwise rejects. Co-authored-by: Isaac
