Promote connector provider infos to a root-level access-review drivers query

Move connectorProviderInfos from Organization to a new root query field
accessReviewDrivers, backed by a deployment-scoped policy so any
authenticated identity can list it without an org-scoped permission check.
Delete the now-unused helper file and update the frontend and e2e tests.
