The function ensure_bits_initialized() in cogl-gl-framebuffer-fbo.c checks for COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS whereas the same in cogl-gl-framebuffer-back.c simply checks for the driver being COGL_DRIVER_GL3. Change the later to use the COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS flag as well. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3047>
