wined3d: Try to detect the polygon offset scale value.

This patch fixes the issue for me. I still have to test it on more drivers
(especially MacOS) to make sure the fix and accompanying test work reliably.

The Nvidia clipping bug was fixed at some point, but as described in the patch
file we run into a different problem that produces the same symptoms now. Using
a better scaling factor for the polygon offset avoids both problems.
