Update D3D10 and D3D11 interop tests (#2479)

Both tests depend on a very old DirectX SDK (August 2009) and expect it
to be extracted to an {NV_TOOLS} environment variable. They additionally
require definining {ARCH} as a CMake configuration option, which is not
needed.

Update both projects to use DirectX libraries provided by the Windows
SDK and drop the unneeded configuration options.
