Merge 236134 "Ensure that the first browser window which is crea..."

> Ensure that the first browser window which is created in Windows 8 ASH is maximized.
> 
> This is done via the Ash WindowPositioner class. The change is in the WindowPositioner::GetBoundsAndShowStateForNewWindow
> function which for windows returns SHOW_STATE_MAXIMIZED if this is the first window being opened.
> 
> Based on a discussion with oshima, I enabled the WindowSizerAshTest ash unit tests for Windows. There were a number
> of places in the WindowSizer class where we were allowing browsers to be in ASH only for Chrome OS. Checking for
> the host desktop type should be enough. This was needed to get the window to be maximized for ASH.
