Thai Nguyen ab953ab8c5 Add flag to add ops to flex delegate allowlist
Usage:
converter = tf.lite.TFLiteConverter.from_keras_model(model)
converter.target_spec.supported_ops = [
    tf.lite.OpsSet.TFLITE_BUILTINS, tf.lite.OpsSet.SELECT_TF_OPS
]
converter.target_spec.select_user_tf_ops = ["UserTFOpname1", "UserTFOpname2"]
