wined3d: Upload directly from the source surface in wined3d_surface_blt(), if possible.
This avoids either loading sysmem surfaces into video memory (wasting GPU memory) and then doing a blit on the GPU, or downloading GPU surfaces to sysmem, doing a blit on the CPU, and likely uploading it again. This mostly matters for ddraw and d3d8 applications, d3d9 already has to go through wined3d_device_update_surface() to transfer data from sysmem surfaces to GPU surfaces.
