[Bug] Support inclusive end time syntax ] in GROUP BY clause IoTDB 2.0.5

### Search before asking

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

### Version

OS: Ubuntu 24.04 LTS
IoTDB: 2.0.5

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

Currently, the `GROUP BY` clause in IoTDB strictly uses the left-closed, right-open `[start, end)` time interval format. Users often need to include the data point exactly at the end time (e.g., `[start, end])`, but the current syntax does not support using `]` to specify an inclusive end time.

When querying time-series data, it is common to want a precise inclusive range (e.g., from `12:00` to `13:00` inclusive). To achieve this now, users must manually extend the end_time by a small fraction (e.g., `+1ms`) or by a full time interval unit, which is unintuitive and can lead to errors or off-by-one queries.

### What did you expect to see?

Support the standard interval syntax `]` to denote an inclusive end time in the `GROUP BY` clause.

Example:
Allow this syntax:
```SQL
SELECT count(s1) FROM root.sg.d1
GROUP BY ([2026-01-27T12:00:00, 2026-01-27T13:00:00], 1m)
```

### What did you see instead?

Current syntex doesn't allow `]` for end time. I have to use the below syntex:

```SQL
SELECT count(s1) FROM root.sg.d1
GROUP BY ([2026-01-27T12:00:00, 2026-01-27T13:00:00), 1m)
```
but it excludes the value at 13:00:00

### Anything else?

Current Workaround:
Users currently have to modify the timestamp manually:
```SQL
-- Extended by 1ms to capture the last point
GROUP BY ([2026-01-27T12:00:00, 2026-01-27T13:00:00.001), 1m)
```

### Are you willing to submit a PR?

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

Bắt đầu bằng cách xác định điểm vào của mệnh đề SQL GROUP BY và cách xử lý các biên cuối của khoảng. Tái hiện các ví dụ trong issue, sau đó xác minh rằng ] đóng được chấp nhận và dữ liệu đúng tại timestamp kết thúc được bao gồm mà không thay đổi hành vi hiện có của [start, end).
