adds ambient occlusion as a client preference (#37406)

ambient occlusion is a shading technique that simulates how light behaves in the real world, where areas that aren't directly exposed to light tend to receive less lighting. In 3d rendered scenes with ambient occlusion present, this can easily be seen in corners and other crevices in geometry, and can also be visible when two objects are close to one another.
