Fix most -Wundef warnings
In some cases #if was used instead of #ifdef in an inconsistent style.
Cleaning this up also helps when analyzing cases like
38d8dce61fff09daae0edb6bcdd42b0c7f10ebcd where this makes a
difference.
There are no behavior changes here, but the change in pg_bswap.h would
prevent possible accidental misuse by third-party code.
