feat(render): tile ambient occlusion

Render smooth lighting ambient occlusion on all Gregtech tiles:
- Ores
- Machines
- Pipes, Cables, Wires, Frames

Add new Client-side configuration entry in Gregtech.cfg.
If false, the flat lighting rendering of older versions is used.

```yml
render {
    B:TileAmbientOcclusion_true=true
}
```
