cuda: Add support for sbsa-linux target

[MaxandreOgeret]

#fix #14981

It adds a new function in the cuda target: _detect_target_path.
And it will search the SBSA target path correctly on aarch64 machines.

Same logic as https://github.com/NVIDIA/cuda-samples/blob/3f1c50965017932fc81e6d94a3fc9e04c105b312/cmake/toolchains/toolchain-aarch64-linux.cmake#L18

Todo:

• Add Arm64 SBSA cuda test

One small implementation nit, otherwise that part looks good.

It would be great to have a test for this as you noted. I'm not sure what our aarch64 CI situation is like these days.

Hey @dcbaker ! Thanks for the review.
I had a talk with @eli-schwartz about aarch64 CI, and the idea was to add a aarch64 docker image and run tests there.
I experimented that in my fork here: MaxandreOgeret@e35c9fd using the ubuntu-24.04-arm runner. But the availability of this runner is sporadic it seems.

Have you thought about it, do you have any hints ?

Eli knows a lot more about how the CI infrastructure works to be honest, and I'd be inclined to defer to his judgement on what we should do there.

I'm happy with the implementation at this point, so I'm fine with merging this now and figuring out CI later, let's see what Eli says.

@MaxandreOgeret can you rebase to clean CI?

[MaxandreOgeret]

Should be good now
