isl/gen8+: Allow 1D and 3D auxiliary surfaces 

Otherwise once mcs buffer gets allocated without delay for lossless
compression (same as we do for msaa), assert starts to fire in
piglit case: tex3d. The test uses depth of one which is in fact
supported even now.

v2 (Jason): Allow also 1D case as there is nothing in the specs
            constraining it either.
