Original issue's description:
> Cros Tablet Window management - Split Screen part II
> 
> Wire up the SplitViewController with the overview mode. It's a following
> up CL of https://codereview.chromium.org/2960843004/.
> 
> Changes in this CL:
> 1. The split view mode can be initiated by dragging the window in
> overview mode to the side of the screen
> 2. After one window is snapped to one side of the screen, all the other
> overview windows will display in the other side of the screen, allowing
> the user to select another window to snap. When two windows are snapped
> to both sides of the screen, the overview mode will be ended.
> 3. The first snapped window will remain snapped until the user
> explicitly exit the split view mode. All the other windows (incluing
> newly created window) will be open in the other side of the screen.
> Clicking/Tapping on the overview button also open the overview windows
> in the other side of the screen.
> 
> Not covered in this CL:
> 1. The highlighted region showing where split will occur is not
>    implemented in this CL.
> 2. The split divider is not implemented in this CL.
