In the next commits I'd like to refactor and fix SYCL libspirv linking. This adds a few tests to cover the current behavior. Some of it is buggy, and not consistent between NVPTX and AMDGPU, it will be improved in the next commits.

This code was basically duplicated between the CUDA and HIP toolchains, and was also present in the Driver sources. This is NFC, aside from the fact that the code in the HIP toolchain lacked the special handling for the `-###` driver option present in the other two places.

This matches the behaviour of SYCL device libraries. The resource directory has nothing to do with libspirv, and it might be changed by the `-resource-dir` option, which would lead us to not find it.
