(PUP-2521) Don't use windows-pr constants

• Somehow there were still some remaining constants referencing Windows:: which is part of windows-pr gem. Most are already defined locally as of the code being ported to FFI. Ensure that we use our internal constant definitions rather than those from gem:
  
  Puppet::Util::Windows::AccessControlEntry::CONTAINER_INHERIT_ACE Puppet::Util::Windows::AccessControlEntry::OBJECT_INHERIT_ACE Puppet::Util::Windows::AccessControlEntry::INHERIT_ONLY_ACE
  
  Puppet::Util::Windows::File::STANDARD_RIGHTS_ALL Puppet::Util::Windows::File::SPECIFIC_RIGHTS_ALL Puppet::Util::Windows::File::FILE_ALL_ACCESS Puppet::Util::Windows::File::FILE_GENERIC_READ Puppet::Util::Windows::File::FILE_GENERIC_EXECUTE
• Add new constants to Puppet::Util::Windows::Error ERROR_FILE_NOT_FOUND ERROR_ACCESS_DENIED
