[FEA]: Make pathfinder usable as a full replacement for cuda_paths.py in numba-cuda #1036
Description
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
Also needed most likely: #759 — Support LoadedDL.from_distribution
This is what we want to replace:

Isn't this a duplicate of #762 + #716?

Thanks for pointing those out! I marked them as sub-issues of this one now.

Do we need duplicate issues tracking this work on both the numba-cuda and cuda-python trackers? It's really difficult to follow the issue true with this duplication. I'm going to close out the numba issue, since this issue is more complete than that one.

Works need to happen in both repos, so I am not sure what's the duplication?

Done as of #716
Delegate all path discovery in cuda_paths.py to pathfinder
