wined3d: Test and fix ddraw and d3d9 GetDC differences.
The MSDN is not totally correct: A8R8G8B8 and A1R5G5B5 also allow GetDC.
The
main differences that have to be filtered out in d3d9.dll are GetDC on
A8B8G8R8, X8B8G8R8 and P8.

Running the ddraw dsurface test seems to indicate that ddraw wants opengl
enabled in the registry as the DirectDrawRenderer. Then when enabling opengl,
a full-screen Seven Kingdoms draws the screen partially offscreen incorrectly.
When virtual desktop is enabled, the game is visible correctly.
Also note, Seven Kingdoms uses an 8-bit color depth.
It is expected that GDI mode should not produce a black screen.
Bug 20327 is similar, but I question whether it is the same problem as it is a
D3D game.
