WL#8326 Make NO_AUTO_CREATE_USER sql_mode behavior the default in 5.7

  * NO_AUTO_CREATE_USER mode added to the default set (compiled-in) of the sql_mode global variable.
  * Server reports missing NO_AUTO_CREATE_USER mode of the sql_mode variable during boot time.
    The initial value of the sql_mode is stored in the configuration file (*.cnf).
  * Switching on and off NO_AUTO_CREATE_USER mode of the sql_mode variable reports warning.
