nit: I think we can remove DragSourceWin, DesktopDragDragSourceWin, etc.

I'm keeping this to just the ui/views changes now. DesktopDragDragSourceWin
seems to have been nuked already, but there was a forward declaration of it that
I'll nuke (in views).

-  DWORD effects;
-  DoDragDrop(ui::OSExchangeDataProviderWin::GetIDataObject(data),
-             drag_source,
-             ui::DragDropTypes::DragOperationToDropEffect(operation),
-             &effects);
-#endif

   float device_scale = GetDeviceScaleForNativeView(widget);
   return new gfx::Canvas(canvas_size, device_scale, false);
 }
