There also is a zero buffer in wgpu-core, I'll see if I can wire that down to these places. |

Description
When creating a BLAS we don't say whether we will be using a transform buffer, but both Vulkan and DirectX check whether the transform buffer (only the transform buffer) is non null. This adds
AccelerationStructureFlags::USE_TRANSFORMwhich is required if building with a transform buffer and disallowed if building without one.Testing
No extra test was added because the transform buffer test was fixed by this (on nVidia).
