Support maxRayRecursionDepth>1 (useful for running some DXR workloads via VKD3D)..

Hi,
can maxRayRecursionDepth be increased to >1 at least like RADV (maxRayRecursionDepth=31) (http://vulkan.gpuinfo.org/displayreport.php?id=24228#properties_extensions)

It useful for running some Microsoft D3D12 DXR samples (https://github.com/microsoft/directx-graphics-samples/blob/master/Samples/Desktop/D3D12Raytracing/src/D3D12RaytracingProceduralGeometry/readme.md) via VKD3D for example..

EDIT:
log from VKD3D:

err:vkd3d-proton:d3d12_state_object_compile_pipeline: MaxTraceRecursionDepth 3 exceeds device limit of 1.

thanks..
