[fix](create table) modify varchar default length 1 to 65533 (#21302)

*modify archer default length 1 to  varchar.max.length , when create table.*

```mysql
create table t2 (             
k1 CHAR,              
K2 CHAR(10) ,               
K3 VARCHAR ,             
 K4 VARCHAR(1024) )              
duplicate key (k1)              
distributed by hash(k1) buckets 1              
properties('replication_num' = '1');  

desc t2;
```
