Description
The test Feature/InlineRT/world-ray-echo.test is failing on AMD DX12 in the driver.
This is due to the Proceed function not being called after TraceRayInline.
However, the whole point of the test is that it should be valid to call functions like RayWorldOrigin(), WorldRayDirection(), RayTMin() and RayFlags() even if Proceed has not been called.
This seems to be a driver bug rather than a bug in the offload-test-suite or the test itself.
Other platforms and even WARP execute this test fine.
Tested on driver 26.6.1

Research direction
Start with Feature/InlineRT/world-ray-echo.test and reproduce the failure on AMD DX12 using driver 26.6.1, comparing it with WARP and other platforms. Done would require determining whether the driver behavior can be fixed in the suite or documenting and escalating the AMD driver issue.
