Subject: [PATCH] Changed the level 0 materials custom commands so that
 materials for all APIs are built. This allows to turn off the OpenGL backend
 (using -DFILAMENT_SUPPORTS_OPENGL=OFF). Previously, disabling the OpenGL
 backend was leading to a compilation error related to missing level 0
 materials.
