anv: Do not sample from 3d depth image with HiZ

For Gen8-11, there are some restrictions around sampling from HiZ.
The Skylake PRM docs for RENDER_SURFACE_STATE::AuxiliarySurfaceMode say:

    If this field is set to AUX_HIZ, Number of Multisamples must
    be MULTISAMPLECOUNT_1, and Surface Type cannot be SURFTYPE_3D.
