[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;
```
| Field | Type | Null | Key | Default | Extra |
| -- |--|--| -| -| -|
| k1 | CHAR(1) | Yes | true | NULL | |
| K2 | CHAR(10) | Yes | false | NULL | NONE |
| K3 | VARCHAR(65533) | Yes | false | NULL | NONE |
| K4 | VARCHAR(1024) | Yes | false | NULL | NONE |
