doc: go/add-power-button-location

changes in this cl:
- Add a switch kAshPowerButtonPosition with value to store the related
  power button position info that read at ChromeOS side.

- Parse the value of the switch in PowerButtonController.

- Get the menu bounds origins in different screen orientations according
  to the position info in PowerButtonMenuScreenView. This will help to
  set the bounds of the menu in each screen orientation.

- Get the menu animation direction and transform distance according to the
  position info in PowerButtonMenuView. We need to minus the animation
  transform when setting the bounds of the menu before showing the menu.
