Adds a benchmark test for opaque solid cubes with dynamic lighting.
Three orbiting light sources illuminate a 16x16x16 cube grid to test
shaded polygon rasterization performance.

- Add LitSolidCubesTest with animated orbiting lights
- Add setViewPanel to BenchmarkTest interface for animation support
- Update benchmark results with new test data
