MDEV-11117 CHECK constraint fails on intermediate step of ALTER

Browse Source 
Fixed the bug by failing the statement with an error message that explains
that an auto-increment column may not be used in an expression for a
check constraint.
Added a test case in check_constraint.test.
Updated existing tests and results.
