This change combines the diffuse/specular light passes into a single texture array, freeing up an image binding for cryptomatte. When diffuse/specular light pass and/or requested a texture array will be allocated. Only when specular light is requested 2 images will always be allocated. This increases the memory overhead when viewing the specular light renderpass in the viewport. For final rendering it is a common scenario that none or both are requested.
