d3d12_platform: ensure windows.h macros don't cause compile errors 

The windows.h macros were undefined only at the end of this platform
header previously but with the addition of d3d12sdklayers.h the
definition of ID3D12DebugQueue::GetMessage picked up the macro and
became GetMessageA or GetMessageW, but Dawn code referred to it as
GetMessage causing a compilation error.

Fix this by preemptively loading windows.h and undefing some of the
macros so that the D3D12 headers don't see them.
