Turns out we were not building OSL with OptiX enabled anymore. Also check now if the OSL builds has OptiX support and if not disable it in Cycles. Building OSL with support for this (still) does not require either the OptiX SDK or CUDA, it only needs LLVM. Pull Request: https://projects.blender.org/blender/blender/pulls/118234
