fix: disable Faiss Python bindings to avoid CMake Python finding issues

- Set FAISS_ENABLE_PYTHON to OFF since we use our own Cython bindings
- This avoids the CMake Python finding issues in manylinux environments
- Simplify CMakeLists.txt by removing unnecessary Python finding logic
- Keep swig installation for other potential uses
