Remove the CCS_D fallback logic so that iris doesn't attempt to use a non-existent surface state for some renders. Also, add an assertion to catch the issue. The fallback in iris_resource_render_aux_usage can lead to this problem because it doesn't account for the fact that surface states created from resources with the Y_TILED_CCS modifier may only have CCS_E or NONE as aux usages (due to iris_resource_create_with_modifiers). Without this change, the next commit would have triggered the fallback and regressed the following tests on gen9: * dEQP-EGL.functional.wide_color.window_888_colorspace_srgb * dEQP-EGL.functional.wide_color.window_8888_colorspace_srgb * dEQP-EGL.functional.wide_color.pbuffer_888_colorspace_srgb * dEQP-EGL.functional.wide_color.pbuffer_8888_colorspace_srgb Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4972>
