Add PI SMM Status Code Protocol on Framework SMM Status Code Protocol thunk driver...

  PI SMM Status Code Protocol on Framework SMM Status Code Protocol Thunk.\r
\r
  This thunk driver produces PI SMM Status Code Protocol and SMM Report Status Code Handler Protocol.\r
  And it registers a status code handler within itself to route status codes into Framework SMM Status\r
  Code Protocol.\r
\r
  Note that Framework SMM Status Code Protocol and PI SMM Status Code Protocol have identical protocol\r
  GUID and interface structure, but they are in different handle databases.\r
