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

21deb57a4d [fix](Nereids) remove double sigature of ceil, floor and round (#22134)
we convert input parameters to double for function ceil, floor and round,
because DecimalV2 could not do these operation. Since we intro DecimalV3,
we should convert all parameters to DecimalV3 to get correct result.
For example, when we use double as parameters, we get wrong result:
```sql
select round(341/20000,4),341/20000,round(0.01705,4);
+-------------------------+---------------+-------------------+
| round((341 / 20000), 4) | (341 / 20000) | round(0.01705, 4) |
+-------------------------+---------------+-------------------+
| 0.017                   | 0.01705       | 0.0171            |
+-------------------------+---------------+-------------------+
```
DecimalV3 could get correct result
```sql
select round(341/20000,4),341/20000,round(0.01705,4);
+-------------------------+---------------+-------------------+
| round((341 / 20000), 4) | (341 / 20000) | round(0.01705, 4) |
+-------------------------+---------------+-------------------+
| 0.0171                  | 0.01705       | 0.0171            |
+-------------------------+---------------+-------------------+
