Merge bitcoin/bitcoin#24837: init: Prevent -noproxy and -proxy=0 from interacting with other settings

3429d67014095b42a976d95c3ef8622d5fe085e6 init: Prevent -noproxy and -proxy=0 settings from interacting with other settings (Ryan Ofsky)

Pull request description:

  Prevent `-noproxy` and `-proxy=0` settings from interacting with `-listen`, `-upnp`, and `-natpmp` settings.

  These settings started being handled inconsistently in the `AppInitMain` and `InitParameterInteraction` functions starting in commit baf05075fae2cc2625a2a74b35cc66902f3cbfa3 from #6272:

  baf05075fa/src/init.cpp (L990-L991)
  baf05075fa/src/init.cpp (L687)

  This commit changes both functions to handle proxy arguments the same way so
  there are not side effects from specifying a proxy=0 setting.

  This change was originally part of #24830 but really is independent and makes more sense as a separate PR
