[PATCH 6/6] dxgi: Get supported feature levels from wined3d caps.

Not much better yet...

The main idea behind the series is to separate feature level checks from
shader model checks in wined3d.

On a side note, handling of feature levels 9_x appears to be incorrect
(AFAIK feature levels 9_x always use SM2 shaders).
