[FEA]: Make `pathfinder` usable as a full replacement for `cuda_paths.py` in `numba-cuda`

[rwgk]

Support for locating these needs to be added:

rwgk-win11.localdomain:/usr/local/cuda-13.0 $ find . -name libdevice.10.bc -o -name nvdisasm -o -name cuobjdump -o -name libcudadevrt.a
./nvvm/libdevice/libdevice.10.bc
./targets/x86_64-linux/lib/libcudadevrt.a
./bin/cuobjdump
./bin/nvdisasm

rwgk-win11.localdomain:/usr/local/cuda-12.9 $ find . -name libdevice.10.bc -o -name nvdisasm -o -name cuobjdump -o -name libcudadevrt.a
./nvvm/libdevice/libdevice.10.bc
./targets/x86_64-linux/lib/libcudadevrt.a
./bin/cuobjdump
./bin/nvdisasm

Sub-issues: #762, #716

Also needed most likely: #759 — Support LoadedDL.from_distribution

This is what we want to replace:
