Revert 182281 - Broke Chome Frame tests.

Revert 182281 - Broke Chome Frame tests.
> Ensure that when themes in desktop chrome AURA on Windows use the opaque browser frame view.
> 
> To achieve this we need to mimic the implementation in BrowserFrameWin::ShouldUseNativeFrame in the
> DesktopBrowserFrameAura::ShouldUseNativeFrame override.
> 
> The code in BrowserFrameWin::ShouldUseNativeFrame has been moved to a helper function in the browser namespace
> ShouldUseNativeFrame in the newly added files browser_frame_common_win.h/.cc. This is invoked from BrowserFrameWin
> and from the BrowserDesktopRootWindowHostWin::ShouldUseNativeFrame override which is invoked via the
> DesktopBrowserFrameAura::ShouldUseNativeFrame override for AURA
