[Bug] AI Node 模型推理结果如何保存回IOTDB以便与真实数据作对比

### Search before asking

- [x] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Version

1.3.3

### Describe the bug and provide the minimal reproduce step

1. 使用以下SQL推理： call inference(_STLForecaster, "select s0,s1,s2 from root.eg.voltage", window=head(96),predict_length=48)
2. 输出数据直接显示到console中
3. 输出数据
1.不能回填到IOT DB
2.不包含时间序列
由于缺少以上功能不便与直接作图对比

### What did you expect to see?

推理输出数据可以指定时间间隔并回填到另外一个time series中

### What did you see instead?

推理输出数据可以指定时间间隔并回填到另外一个time series中

### Anything else?

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Reproduce the CALL inference(_STLForecaster, ...) query from the issue and inspect how its output is produced and returned to the console. Trace the inference entry point and determine how an interval and destination time series could be represented. Done means inference results retain timestamps and can be written to another IoTDB time series for comparison with real data.
