Fix error message for ALTER CONSTRAINT ... NOT VALID

Browse Source 
Trying to alter a constraint so that it becomes NOT VALID results in an
error that assumes the constraint is a foreign key.  This is potentially
wrong, so give a more generic error message.

While at it, give CREATE CONSTRAINT TRIGGER a better error message as
well.
