FAISS CUDA 12 support for benchmarks.

[bdice]

In PR #1388, we cannot yet enable CUDA 12 support for benchmarks with FAISS because the packages on conda-forge lack CUDA 12 support. This issue tracks that. We can resolve this by enabling CUDA 12 FAISS benchmarks once packages are available.

FWIW here's the FAISS CUDA 12 migration PR ( conda-forge/faiss-split-feedstock#68 ). If someone would like to chip in there, that would be greatly appreciated 🙂
