Replace python dependency with Faiss JLL

[stemann]

It might soon be possible to replace the PythonCall-approach with a JLL: JuliaPackaging/Yggdrasil#8483

If have a jll version, that would be great. hope the interface to align with python's faiss.

The easy way would be to use the C API (wrapped via Clang.jl): https://github.com/facebookresearch/faiss/blob/main/c_api/INSTALL.md#using-the-api

On a related note, I see there is already CUDA/GPU support in Faiss.jl, so I guess that would be a requirement for JuliaPackaging/Yggdrasil#8483 - in order to provide a drop-in replacement for using the Python API.
