Removing the GetUndocumentedDPIScale and GetUndocumentedDPITouchScale methods from ui/gfx/win/dpi.cc/.h as these are no longer needed given that Chrome is now HiDPI aware.
On the same lines removed some code from the GetMinimizeButtonOffsetForWindow function for window which
attempts to workaround some issues with Surface Pro. This is also not needed given that we are HiDPI aware.
