ddl: make 'alter table reorganize partition' report error (#17020)

[sre-bot]

cherry-pick #17020 to release-4.0

---

What problem does this PR solve?

create table t ( id int, fname varchar(25), lname varchar(25), dob date) partition by range( year(dob) ) (
    partition p0 values less than (1980),
    partition p1 values less than (1990),
    partition p2 values less than (2000),
    partition p3 values less than maxvalue
);

alter table t reorganize partition p0 into (
    partition n0 values less than (1970),
    partition n1 values less than (1980)
);

This operation is not supported yet, return an error explicitly is better that simply ignore the statement.
