Merge #5205

5205: Incremental facets on v1.12 r=curquiza a=dureuill

# Pull Request

## Related issue

Fixes https://github.com/meilisearch/meilisearch/issues/5213

## What does this PR do?
- Add `new_incremental`module that computes incremental facet indexing for the new indexer
- Change heuristics for incremental vs bulk facet choice: under 1000 operations is now always incremental, over 100_000 operations is now always bulk)
- Add sanity checks in debug

## Future improvements

- Use multi ops from Roaring to decrease the number of allocations
- Consider removing or adding multiple levels at once instead of max once per update
- Consider using information about the tree structure + the operations that were done (e.g. only addition) to avoid recomputing the group from all children 
- Consider making the algorithm parallel and looking into the roaring values to know which actually changed

+You can set the `LINDERA_CACHE` environment variable to speed up your successive builds by up to 2 minutes.
