Reorder code in pg_dump to dump comments etc in a uniform order.
Most of the code in pg_dump dumps an object's comment, security label, and ACL auxiliary TOC entries, in that order, immediately after the object's main TOC entry, and at least dumpComment's API spec says this isn't optional. dumpDatabase was significantly violating that when in binary-upgrade mode, by inserting totally unrelated stuff between. Also, dumpForeignDataWrapper and dumpForeignServer were being randomly inconsistent. Reorder code so everybody does it the same. This may be future-proofing us against some code growing a requirement for such auxiliary entries to be adjacent to their main entry. But for now it's just neatnik-ism, so I see no need for back-patch. Discussion: https://postgr.es/m/21714.1516553459@sss.pgh.pa.us
