In case vk_color_attachment_location_state is in its default state, we
would end up with an identity mapping for color_map resulting in 8 RTs
being selected instead of what is really required.
This now use the rendering state attachment count to properly emit
SET_CT_SELECT.
Found while debugging MRT on
"dEQP-VK.shader_object.rendering.color_attachment_count_1.extra_attachment_after_1.none.none.same_color_formats.after.none.r16g16_sint_d32_sfloat_s8_uint"
and while comparing with the proprietary driver.
