[Fix](Outfile) The Struct type data exported from select outfile to the csv file format should contain a column name

[BePPPower]

Proposed changes

Issue Number: close #xxx

If the original data is：

+-----------------------------------------------------+
| s_info                                              |
+-----------------------------------------------------+
| {"s_id": 2, "s_name": "nereids", "s_address": "20"} |
| {"s_id": 1, "s_name": "doris", "s_address": "18"}   |
+-----------------------------------------------------+

In the original logic, the struct type data exported to a csv file format did not contain column names,like

{2, "nereids", "20"} 
{1, "doris", "18"}

This pr do not need to be merged into branch-2.0
