Improve the 3D graphics settings demo

- New graphics settings:
  - Field of view.
  - Volumetric fog.
- Use Godot's built-in 3D viewport facilities instead of using a SubViewport.
  - This also allows for choosing AMD FidelityFX Super Resolution
    for resolution scaling, but it's not working yet due to a Godot bug.
  - Nearest-neighbor scaling is no longer available. It can be
    reimplemented in Godot core and then exposed in the future.
- Separate MSAA from FXAA settings, as both can be used at the same time.
- Add more quality settings for various effect settings.
- Rename sections and setting names to be more "player-oriented"
  (even if this results in the actual Godot terminology not being
  presented).
- Add performance hints to setting values.
- Add FPS counter and viewport resolution display
  (taking the resolution scale into account).
- Add more objects to the test scene and tweak environment settings.
  - ACES tonemapping is now used.
  - Debanding is now enabled, as this scene requires it to avoid visible
    banding.
  - Make the emissive box less bright to prevent MSAA and FXAA from
    being ineffective on it (due to Godot not supporting correct
    HDR antialiasing).
  - Remove unnecessary DirectionalLight3D, VoxelGI and ReflectionProbe.
