Merge #17567: gui: remove macOS start on login code

27d82b63fb8869716d2f103fd381c2413bde4d1b gui: remove macOS start on login code (fanquake)

Pull request description:

  The macOS startup item code was disabled for builds targeting macOS >
  `10.11` in #15208. Now that we require macOS `10.12` as a minimum (#17550),
  we can remove the startup item code entirely. The API we were using, `LSSharedFileListItemCopyResolvedURL`, `LSSharedFileListCopySnapshot` etc,
  was removed in macOS `10.12` SDK.
