[BUG]: thrust::cuda_cub::launcher::triple_chevron is called in headers even for non CUDA compilers #3376

Compile-time Error
Component
Thrust
Describe the bug
When compiling cuGraph code with a recent CCCL, some .cpp file compiled with a non CUDA compiler includes headers which eventually include headers that do need a CUDA compiler.
I am not sure if the problem is in RAFT, RMM, Thrust or CUB here ! Maybe some additional safeguard in CCCL headers would be helpful to detect we are using an inappropriate compiler earlier in the list of nested includes ?

How to Reproduce
Compile the cpp lib for that branch which updates CCCL in cuGraph rapidsai/cugraph#4833
Expected behavior
The RAFT header should be compilable from any compiler, or report some error earlier
