The final candidate of the version that uses Faiss 1.7.4

[alexanderguzhva]

Finalized version of #90
Based on Faiss 1.7.4 (based on commit c8d6f7bb2b09b8928570222131353f75acb4007b from Sep 6 2023, but with all the most recent merged commits).

Issue #186

The following changes were made to Knowhere besides refactoring:

• All BitsetView filtering is replaced with faiss::IDSelector filtering.
• So-called “thread-safe” functions were deleted. Instead, regular search()/range_search() are used with faiss::SearchParameters objects as a function parameter.
• faiss::elkan_L2_sse() call is used by default as before, but IVF-indices in Knowhere (ivf.cc) introduce a new flag “use_elkan” (false by default), which allows to significantly speed up the training

@alexanderguzhva 🔍 Important: PR Classification Needed!

For efficient project management and a seamless review process, it's essential to classify your PR correctly. Here's how:

1. If you're fixing a bug, label it as kind/bug.
2. For small tweaks (less than 20 lines without altering any functionality), please use kind/improvement.
3. Significant changes that don't modify existing functionalities should be tagged as kind/enhancement.
4. Adjusting APIs or changing functionality? Go with kind/feature.

For any PR outside the kind/improvement category, ensure you link to the associated issue using the format: “issue: #”.

Thanks for your efforts and contribution to the community!.
