[SPIR-V] Accessing HitTriangleVertexPositionsKHR fails

13

**Description** [SPV_KHR_ray_tracing_position_fetch](https://github.com/KhronosGroup/SPIRV-Registry/blob/main/extensions/KHR/SPV_KHR_ray_tracing_position_fetch.asciidoc) is adding a new `HitTriangleVertexPositionsKHR` built-in, but even with the use of `[[vk::ext_decorate]]`, it does not seem possible to access the values in a HLSL Closest-Hit shader. **Steps...

It should test if all attribute accessors in a given node must have the same count. Reference: https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Vendor/EXT_mesh_gpu_instancing/README.md
