At present, create basic tables such as orc/parquet with partition transform
will succeed. However, we only support iceberg tables for partition transform
now, so i think we need to throw a friendly exception if the table does not
support partition transform, to avoid user misunderstanding that the basic
tables have such ability.
We can throw friendly exception to client if the table does not support
partition transform, such as the following exception:
```
0: jdbc:hive2://127.0.0.1:10000/default> create table customer(customer_id
int,first_name string,last_name string) partitioned by spec(TRUNCATE(2,
last_name)) stored as orc;
Error: Error while compiling statement: FAILED: SemanticException Partition
transform is only supported for specific storage handler tables. e.g. Iceberg
tables (state=42000,code=40000)
```

Throw friendly exception if the table does not support partition transform
