Well, aside from indirect inclusions, pg_type.h also brings in a bunch
of type OID macros, which I feel we don't want to broadcast everywhere.

One argument in favor of sticking these new macros somewhere "more
central" is that they apply to both pg_type and pg_attribute (that
is, attalign and attstorage also use them).  That's not a strong
argument, maybe, but it's something.
