[PATCH v2] dxgi/tests: Check that the last adapter is always WARP.

[Zhiyi Zhang]

From: Rémi Bernon

Some games specifically ignore the last adapter from the adapter list,
as it's always WARP on Windows. This makes them fail to detect GPUs
correctly on Wine, as they drop one of the reported adapters.

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

As predicted, this fails here on Windows 7.

I guess a broken/win_skip would be appropriate?.
