    During lowering from a `tf_device.cluster_func` op to a `tf.IfrtCall` op,
    the region owned by the former will be outlined to a function with a
    `tfrt_ifrt_serving.program_id` attribute. After that, the runtime ensures
    that the outlined function is compiled into an executable and is available
    for lookup from `IfrtCall` TF ops.
