Philip Rideout bf34ee6e22 gltfio: add multi-scene support. (#5524) ...

* Add multi-scene support to gltf_viewer.

To test this, I generated a multi-scene asset as follows.

```
gltf-transform merge Avocado/glTF/Avocado.gltf \
    BarramundiFish/glTF/BarramundiFish.gltf \
    ~/Desktop/Merged.gltf
```

* Specify c++17 in pbxproj files.
