pgsql: Refactor ObjectAddress field assignments in more places

Refactor ObjectAddress field assignments in more places

This is a follow-up commit similar to 68de144, with more places in the
backend code simplified with the macros able to assign values to the
fields of ObjectAddress. The code paths changed here could be
transitioned later into using more grouping when inserting dependency
records, simplifying this future work.
