[Bug 51181] d3d10core:d3d10core fails systematically on AMD GPUs

Some comments:

  - From the results, it looks like the affected configurations are mishandling
the instance data step rate of "2", instead behaving as if it was "0". In
principle that would warrant a broken(), but there's also a small chance it
could be avoided by using a different vertex data format like
DXGI_FORMAT_R8G8B8A8_UNORM instead of DXGI_FORMAT_R8_UNORM. If the latter
works, that would probably be preferred.

  - This test has a d3d11 equivalent, and the affected configurations are
failing in the same way there.

  - It's perhaps overly broad to say "AMD GPUs". At first sight, the only AMD
results we have on test.winehq.org are the win*_cw-rx460-*, and
win2009_fgtb-*-rx550-* results. The "rx460" appears to actually be an RX 560,
but in any case, those are all AMD POLARIS cards. On the other hand, these are
certainly succeeding on my AMD GPU here, and presumably they were for Józef
when he wrote that test.
