vk: Don't duplicate anv_depth_stencil_view's surface data

In anv_depth_stencil_view, replace the members
    bo
    depth_offset
    depth_stride
    depth_format
    depth_qpitch
    stencil_offset
    stencil_stride
    stencil_qpitch
with the single member
    const struct anv_image *image

The removed members duplicated data in anv_image::depth_surface and
anv_image::stencil_surface.
