Jibing-Li 3fe419eafa [Fix](statistics)Fix update cached column stats bug (#23049)
`show column cached stats` sometimes show wrong min/max value:
```
mysql> show column cached stats hive.tpch100.region;
+-------------+-------+------+----------+-----------+---------------+------+------+--------------+
| column_name | count | ndv  | num_null | data_size | avg_size_byte | min  | max  | updated_time |
+-------------+-------+------+----------+-----------+---------------+------+------+--------------+
| r_regionkey | 5.0   | 5.0  | 0.0      | 24.0      | 4.0           | N/A  | N/A  | null         |
| r_comment   | 5.0   | 5.0  | 0.0      | 396.0     | 66.0          | N/A  | N/A  | null         |
| r_name      | 5.0   | 5.0  | 0.0      | 40.8      | 6.8           | N/A  | N/A  | null         |
+-------------+-------+------+----------+-----------+---------------+------+------+--------------+
```
This pr is to fix this bug. It is because while transferring ColumnStatistic object to JSON, it doesn't contain the minExpr and maxExpr attribute.
