63b61e9 Remove delete match arm and match guard mutation exclusion (user)

Pull request description:

  Closes rust-bitcoin#4653
  
  This removes the delete match arm and match guard exclusion as these mutations can now be targeted individually.
  
  ~~In draft as I have yet to run the mutations locally to add any exclusions that may still need to be added~~
