test(rt): read the TLAS from the descriptor heap, with a probe for the NVIDIA fault HeapASRead renders a triangle, tracing half the frame with traceRayEXT and ray querying the other half, both reading the TLAS out of the descriptor heap, and checks the read-back pixels. The test runner runs it through the engine's normal path, so on NVIDIA it covers the rewrite too: an inherited CRAFTER_GRAPHICS_NO_AS_WORKAROUND is cleared, and the test checks the rewrite is on exactly where the driver needs it. HeapASRead --no-workaround is the check for a newer driver. Each path renders in its own child process with the rewrite off and validation off (GPU-assisted validation instruments the shaders), so a device loss on one doesn't hide the other. On 615.78.08 traceRayEXT still loses the device and the ray query renders nothing.
