Debug Assert ala debug printf feature

I don't think I saw a feature request for this. Basically debug assert in the same way debug printf works. The ability to make a dispatch/draw stop if an assertion isn't met at runtime inside of a shader. ie how CUDA's assert works. https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#assertion

Review the CUDA assertion reference linked in the issue and the surrounding Vulkan-Docs issue context; no files, tests, or entry points are identified. Clarify with maintainers whether the goal is a Vulkan API/specification change and define the required runtime behavior and acceptance criteria before implementation.
