CUDA: More exhaustive checks to determine when to do device linking

Previously CMake used fairly naive logic to determine when to do
device linking which caused unnecessary device linking to occur
frequently. We now use a more exhaustive algorithm to determine
when we have a need for device linking.

Fixes: #19238
