CUDA: Clang separable compilation

For NVCC the compiler takes care of device linking when passed the "-dlink"
flag.
Clang doesn't support such magic and requires the buildsystem to do the work
that NVCC does behind the scenes.

The implementation is based on Bazel's device linking documentation:

Closes: #20726
