Bug: b:130291631

Original change's description:
> Chrome OS: Add DOM |code| mappings for new action keys.
> 
> Wilco emits action key codes directly from kernel instead of
> function-key codes. This CL adds new Dom codes or fixes existing Dom
> codes accordingly. They are:
> 
> key code             Dom code
> -----------------------------------------------------
> KEY_SCALE            SHOW_ALL_WINDOWS (new)
> KEY_SWITCHVIDEOMODE  DISPLAY_TOGGLE_INT_EXT (new)
> KEY_ZOOM             ZOOM_TOGGLE (fix evdev/xkb value)
> KEY_ASSISTANT        LAUNCH_ASSISTANT (fix HID value)
> 
> Also removed invalid dom-code values for ZOOM_TOGGLE and
> LAUNCH_ASSISTANT.
