Merge #15358: util: Add SetupHelpOptions()

a99999cc04c2e7d79bb841fd954c84e985ed3b88 util: Add SetupHelpOptions() (MarcoFalke)

Pull request description:

  Every binary we have sets up the help option in their own way and wording.

  Solve that by having one function take care of it for all of them.
