Remove unnecessary code to handle CONSTR_NOTNULL

Commit 14e87ffa5c54 needlessly added support for CONSTR_NOTNULL entries
to StoreConstraints.  It's dead code, so remove it.

To make the situation regarding constraint creation clearer, change
comments in heap_create_with_catalog, StoreConstraints, MergeAttributes
to explain which types of constraint are used on each.
