Like the previous patch in the series, this causes issues in the
corresponding d3d10core tests.

I think it's a little ugly to set this flag using the
format_texture_info[] array. Using format_base_flags[] seems more
appropriate, and would have the advantage of working with the Vulkan
backend as well.
