sql: disallow UDF in SET DEFAULT and SET ON UPDATE

Release note (sql change): previously users were able to sneak
in UDF usage from tables with `SET DEFAULT` and `SET ON UPDATE`
even they are disallowed from `CREATE TABLE` and `ADD COLUMN`.
This patch disallows those two cases from `ALTER TABLE ALTER COLUMN`.
