4713: Speed up facet distribution r=ManyTheFish a=Kerollmops
This PR is akin to #4682, but this time, the same logic is applied to the facets. Bitmaps are not decoded, and we do an intersection on the bytes with the search candidates instead of materializing the RoaringBitmap to destroy it just after the operation.
A prospect raised some slow requests when performing facet searches, and I found out that the disk optimization intersection wasn't performed on the facets.

4693: Introduce distinct attributes at search time r=irevoire a=Kerollmops
This PR fixes#4611.
### To Do
- [x] Remove the `distinguishableAttributes` settings (not even a commit about that).
- [x] Use the `filterableAttributes` to be able to use the `distinct` parameter at search.
- [x] Work on the errors and make tests.

4649: Don't store the vectors in the documents database r=dureuill a=irevoire
# Pull Request
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/4607
## What does this PR do?
- Ensure that anything falling under `_vectors` is NOT searchable, filterable or sortable
- [x] per embedder, add a roaring bitmap of documents that provide "userProvided" embeddings
- [x] in the indexing process in extract_vector_points, set the bit corresponding to the document depending on the "userProvided" subfield in the _vectors field.
- [x] in the document DB in typed chunks, when writing the _vectors field, remove all keys corresponding to an embedder

- when the feature is disabled, documents are never modified
- when the feature is enabled and `retrieveVectors` is disabled, `_vectors` is removed from documents
- when the feature is enabled and `retrieveVectors` is enabled, vectors from the vectors DB are merged with `_vectors` in documents
Additionally `_vectors` is never displayed when the `displayedAttributes` list does not contain either `*` or `_vectors`
- fixed an issue where `_vectors` was not injected when all vectors in the dataset where always generated

4682: Speed Up Filter ANDs operations r=Kerollmops a=Kerollmops
This PR fixes#4659 and improves the way we do AND operations by using the latest [RoaringBitmap feature to do intersections with serialized bitmaps](https://github.com/RoaringBitmap/roaring-rs/pull/281). Doing so drastically reduces the time spent reading, copying bytes in memory to use and keep a subset of the containers in the bitmap.
### Some Example Results
With a 45M documents dataset running on a good NVMe. This example filter was taking 77ms and with this PR only 13ms (6x speedup):
```sql
artist = 'The Beatles' AND (duration 150 TO 500 OR duration NOT EXISTS) AND genres IN [Rock, 'Rock and Roll'] AND rating > 4 AND released_year 1960 TO 1990
```
By reordering the filter AND clauses we can reach a constant 8ms execution time. However, note that it is a manual operation. On the other side the previous filter pipeline is still at a constant 45ms execution time with this filter. (6x speedup)
```sql
artist = 'The Beatles' AND genres IN [Rock, 'Rock and Roll'] AND released_year 1960 TO 1990 AND (duration 150 TO 500 OR duration NOT EXISTS)
```
### To Do
- [x] Rebase on `release-v1.9.0`.
- [ ] ~Skip branches of the facet/filter tree when nothing is in common with the universe~ slower this way.
- [x] When the universe is required use the universe given in parameter if possible.
