[PATCH 4/5] wined3d: Add texture flag for mipmap generation.

[Matteo Bruni]

Tests (later on in the patch series) show that calling GenerateMips()
on a texture without the D3D11_RESOURCE_MISC_GENERATE_MIPS flag does
nothing.  In theory, the whole check could be done on the d3d11 side
but that turns out to be somewhat awkward, in practice, so I'm going
to add a wined3d flag and pass it around instead.
