Execution of this query
```
create table t (c1 int(11) DEFAULT 1 NULL) engine=MergeTree order by tuple()
```
will return parsed query
```
CREATE TABLE t
(
     `c1` int NULL DEFAULT 1
)
ENGINE = MergeTree
ORDER BY tuple()
```
In the parsed query, NULL comes before DEFAULT, in the initial - other way around.
If I try to execute the parsed query, I’ll get the following error:
```
Syntax error: failed at position 36 ('DEFAULT') (line 3, col 19):

CREATE TABLE t
(
    `c1` int NULL DEFAULT 1
)
ENGINE = MergeTree
ORDER BY tuple()

Expected one of: COMMENT, CODEC, TTL, token, Comma, ClosingRoundBracket
```
This is confusing.

Considerations:
(1) considering simplification of migration from other databases (see, for example, #37178) probably it makes sense to keep support for old column declaration, - MySQL supports both ways: `NULL DEFAULT 1` and `DEFAULT 1 NULL`, even `COMMENT '1' NULL` which we don't support. This way it'll keep the change backward compatible
(2) from another side ... I guess ... there is no target to support all variants of different syntax. It's not desirable to complicate parser implementation just for this reason
