    framebuffer: Only remember offscreen allocate flags when !COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL
    
    Otherwise, if a texture is created before all the other FBOs, a new
    atlas will be created, with a FBO with COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL
    causing last_offscreen_allocate_flags to be 0.
