Update: For Moto G 2015 (Moto G 3rd Gen) or Moto X 3rd Gen (Moto X Pure edition, Moto X Style and Moto X Play), because Android Lollipop 5.1 is pre-installed, you should be able to find the icon in quick settings panel. If not, you can also follow this guide to enable the auto-rotate screen option.
