ddraw: Implement FPU mode fixup in d3d7 device.

As documented in DirectX7 SDK, d3d7 devices set FPU mode (control word) on every 
call and restore it back to original state before returning, if created in 
DDSCL_FPUPRESERVE cooperative mode. This allows games to work with FPU in a 
possibly incompatible mode and avoid resetting it all the time.
