pgsql: Refactor ObjectAddress field assignments for type dependencies

Refactor ObjectAddress field assignments for type dependencies

The logic used to build the set of dependencies needed for a type is
rather repetitive with direct assignments for each ObjectAddress field.
This refactors the code to use the macro ObjectAddressSet() instead, to
do the same work. There are more areas of the backend code that could
use this macro, but these are left for a follow-up patch that will
partially rework the way dependencies are recorded as well. Type
dependencies are left out of the follow-up patch, so they are refactored
separately here.

Extracted from a larger patch by the same author.
