morrySnow eed72a101e [fix](Nereids) decimalv3 cast in fe produce wrong data (#29808) ...

case:
```
MySQL root@127.0.0.1:test> select cast(12 as decimalv3(2,1))
+-----------------------------+
| cast(12 as DECIMALV3(2, 1)) |
+-----------------------------+
| 12.0                        |
+-----------------------------+
```

decimalv2 literal will generate wrong result too. But it is not only
bugs in planner, but also have bugs in executor. So we need fix executor
bug in another PR.
