[PATCH 1/3] ddraw/tests: Use a TnLHal device only if supported in ddraw7 tests.

[Stefan Dösinger]

Intel GPUs don't support d3d7 hardware vertexprocessing on Windows. In
d3d8 and d3d9 it is available starting with i965 chips, but for some
reason the driver does not expose this for d3d7.

The other ddraw tests always use software vertexprocessing, I see no
reason to change this at this point.
