pg_dump: Tiny header cleanup

Browse Source 
In commits 9c02e3a986da and 8ec0aaeae094, Nathan added a duplicate
TocEntry typedef forward declaration (plus assorted #ifdef hackery to
avoid C99 preprocessor issues) to deal with some very old untidyness
regarding DefnDumperPtr function prototype being located in pg_backup.h.
But there's no reason to have the DefnDumperPtr typedef (and the
accompanying DataDumperPtr typedef) in that file at all; they are better
placed in pg_backup_archiver.h, the internal header, because they are
only used internally.  That also requires zero #ifdef hackery, so move
them there.
