RFR: 8285534: Update the 3D lighting test sample

[Nir Lisker]

Update the the test utility. Includes:
* Refactoring since there is no more need the split pre- and post-attenuation and light types.
* Added customizable material to the `Boxes` to test the interaction between lights and materials..
* Light colors can now be changed.

Note that GitHub decided to count the removal of the `AttenLightingSample` and addition of the `Controls` file as renaming. The sample is now run now only through `LightingSample`.
