Use backup DC for D3D devices created using desktop window

One more patch from me. This time I'm switching to a dummy window (swapchain's
backup DC) when the desktop window handle is passed to
IDirect3D9::CreateDevice.

This solution is much cleaner that my previous patch.

Tested on Napoleon: Total War - no glitches at full details (including SSAO and
HDR).
