Revert "intel/isl: Only create a CCS buffer if the image supports rendering"

This reverts commit 8aaa13467dc289d35dc7900ab9fab9a7689c4178, which was
based on an incorrect assumption. Unlike the restriction placed on image
views in the Vulkan API, OpenGL allows you to render to texture views
whose formats differ from the originals.
