268c867679 [Improve](serde)replace function_cast from_string to serde (#24087) 
Now we can not support streamload with column which is map/array nested map/array
serde can do this now , so we can replace it
Notice. if item data in complex type data is empty we just return error, instead of makeup default value , because now we can not define right default for complex type

d76fa427a3 [improve](jsonb)Invalid json path prompts an error instead of null (#19646) 
1. Invalid json path prompts an error instead of null：
before：
```sql
mysql> SELECT jsonb_extract('[{"k1":"v41","k2":400},1,"a",3.14]', '$[a]');
+-------------------------------------------------------------+
| jsonb_extract('[{"k1":"v41","k2":400},1,"a",3.14]', '$[a]') |
+-------------------------------------------------------------+
| NULL                                                        |
+-------------------------------------------------------------+
1 row in set (0.01 sec)
```
now
```sql
mysql> SELECT jsonb_extract('[{"k1":"v41","k2":400},1,"a",3.14]', '$[a]');
ERROR 1105 (HY000): errCode = 2, detailMessage = (127.0.0.1)[INVALID_ARGUMENT]Json path error: Invalid Json Path for value: $[a]
```
2. fix some problem: https://github.com/apache/doris/pull/19185
   a. support negative numbers
```sql
mysql> SELECT jsonb_extract('[{"k1":"v41","k2":400},1,"a",3.14]', '$[-2]');
+--------------------------------------------------------------+
| jsonb_extract('[{"k1":"v41","k2":400},1,"a",3.14]', '$[-2]') |
+--------------------------------------------------------------+
| "a"                                                          |
+--------------------------------------------------------------+
1 row in set (0.02 sec)
```

294599ee45 [feature](jsonb) rename JSONB type name and function name to JSON (#19774) 
To be more compatible with MySQL, rename JSONB type name and function name to JSON.

The old JSONB type name and jsonb_xx function can still be used for backward compatibility.

There is a function jsonb_extract remained since json_extract is used by json string function and more work need to change it. It will be changed further.
