  [dmd-cxx] fix Issue 21726 - Wrong comparison in package(...) visibilities

  For the purpose of creating a new scope, it makes no sense to let the
  most restrictive package attributes override any other nested visibility
  attributes.  As there is no other use of isSubsetOf(), the entire
  function has been removed.
