[Fix](Planner) fix parse error of view with group_concat order by (#22196)

Problem:
    When create view with projection group_concat(xxx, xxx order by orderkey). It will failed during second parse of inline view

For example:
    it works when doing 
    "SELECT id, group_concat(`name`, "," ORDER BY id) AS test_group_column FROM  test GROUP BY id"
    but when create view it does not work
    "create view test_view as SELECT id, group_concat(`name`, "," ORDER BY id) AS test_group_column FROM  test GROUP BY id"

Reason:
    when creating view, we will doing parse again of view.toSql() to check whether it has some syntax error. And when doing toSql() to group_concat with order by, it add seperate ', ' between second parameter and order by. So when parsing again, it
would failed because it is different semantic with original statement.
    group_concat(`name`, "," ORDER BY id)  ==> group_concat(`name`, "," , ORDER BY id)

Solved:
    Change toSql of group_concat and add order by statement analyze() of group_concat in Planner cause it would work if we get order by from view statement and do not analyze and binding slot reference to it
