### What problem does this PR solve?
This pr mainly solves the problem when we insert top-level nested array data
into variant columnIssue Number:
like :
```
mysql> insert into sv1 values (1, '[{"a": 1, "c": 1.1}, {"b": "1"}]');
we maintain the association information between Nested in array , in this
case , we will keep same offset at a,b,c ,
mysql> select * from sv1;
+------+----------------------------------------------+
| k | v |
+------+----------------------------------------------+
| 1 | {"a":[1,null],"b":[null,"1"],"c":[1.1,null]} |
+------+----------------------------------------------+
```
but in top array we just do flatten array not fill the null value to
maintain the association information between Nested in array
like:
```
mysql> insert into sv1 values (16, '[{"a": 1, "b": 1}, {"b": 2}, {"b": 3}]');
Query OK, 1 row affected (0.15 sec)
{'label':'label_4b3ede8b449a4d9a_b55fdeebe13b741c', 'status':'VISIBLE',
'txnId':'6031'}
mysql> select v from sv1 where k=16;
+-----------------------+
| v |
+-----------------------+
| {"a":[1],"b":[1,2,3]} |
+-----------------------+
1 row in set (0.19 sec)
