Vulkan Ray Tracing: Deprecating Host-Side Acceleration Structure Builds

Vulkan is deprecating host-side ray tracing acceleration structure build commands in favor of a single, device-address-based path. This aligns Vulkan Ray Tracing with the direction of DirectX Raytracing, modern engine architecture, and hardware trends.In the six years since Vulkan Ray Tracing launched, the host-side path has seen limited adoption. Developers generally found it more cumbersome than helpful, while implementers had to maintain parallel host/GPU command models that increased complexity and created friction for future ray tracing API evolution.
