Add Section For Buffer Device Address and Vertex Pulling

Maybe it would make sense to add an additional chapter that introduces vertex pulling + buffer device address as an alternative to the traditional vertex buffer + descriptor path?

The motivation being:

closer to modern engine architectures (GPU-driven, bindless-style data)

aligns with patterns used in ray tracing and mesh/task workflows

gives a more “direct memory access” model (somewhat CUDA-like)

useful for large-scale transform / vertex data handling

The existing path is great for teaching core Vulkan concepts — but adding a “Vertex Pulling with Device Address” section could be really valuable?

Start by reviewing the existing tutorial’s traditional vertex-buffer and descriptor path, then determine the scope and teaching sequence for a vertex-pulling and buffer-device-address section. Done means a complete, integrated tutorial chapter that explains the alternative workflow and its relationship to the existing path.
