4900: Indexer edition 2024 r=Kerollmops a=dureuill

This PR is implementing the indexer edition 2024, largely inspired by [the ideas from this blog post](https://blog.kerollmops.com/meilisearch-is-too-slow).

Fixes https://github.com/meilisearch/meilisearch/issues/4985

## Features
- Stream-first approach to reading documents.
- Minimum disk write operations.
- RAM usage-first approach to avoid modifying common bitmaps on disk but in memory.
- Reduced LMDB fragmentation by writing entries only once...
- ...computing the final version of the entries in parallel...
- ...and storing them in write-optimized data structures before sending them to the BTree (LMDB).
- Indexing in multiple transactions to improve large dataset support (dumps).

//! # How the Merge Algorithm works
//!
//! Each extractor create #Threads caches and balances the entries
//! based on the hash of the keys. To do that we can use the
//! hashbrown::hash_map::RawEntryBuilderMut::from_key_hashed_nocheck.
//! This way we can compute the hash on our own, decide on the cache to
//! target, and insert it into the right HashMap.
//!
//! #Thread -> caches
//! t1 -> [t1c1, t1c2, t1c3]
//! t2 -> [t2c1, t2c2, t2c3]
//! t3 -> [t3c1, t3c2, t3c3]
//!
//! When the extractors are done filling the caches, we want to merge
//! the content of all the caches. We do a transpose and each thread is
//! assigned the associated cache. By doing that we know that every key
//! is put in a known cache and will collide with keys in the other
//! caches of the other threads.
//!
//! #Thread -> caches
//! t1 -> [t1c1, t2c1, t3c1]
//! t2 -> [t1c2, t2c2, t3c2]
//! t3 -> [t1c3, t2c3, t3c3]
//!
//! When we encountered a miss in the other caches we must still try
//! to find it in the spilled entries. This is the reason why we use
//! a grenad sorter/reader so that we can seek "efficiently" for a key.
//!
//! ## More Detailled Algorithm
//!
//! Each sub-cache has an in-memory HashMap and some spilled
//! lexicographically ordered entries on disk (grenad). We first iterate
//! over the spilled entries of all the caches at once by using a merge
//! join algorithm. This algorithm will merge the entries by using its
//! merge function.
//!
//! Everytime a merged entry is emited by the merge join algorithm we also
//! fetch the value from the other in-memory caches (HashMaps) to finish
//! the merge. Everytime we retrieve an entry from the in-memory caches
//! we mark them with a tombstone for later.
//!
//! Once we are done with the spilled entries we iterate over the in-memory
//! HashMaps. We iterate over the first one, retrieve the content from the
//! other onces and mark them with a tombstone again. We also make sure
//! to ignore the dead (tombstoned) ones.
//!
//! ## Memory Control
//!
//! We can detect that there are no more memory available when the
//! bump allocator reaches a threshold. When this is the case we
//! freeze the cache. There is one bump allocator by thread and the
//! memory must be well balanced as we manage one type of extraction
//! at a time with well-balanced documents.
//!
//! It means that the unknown new keys added to the
//! cache are directly spilled to disk: basically a key followed by a
//! del/add bitmap. For the known keys we can keep modifying them in
//! the materialized version in the cache: update the del/add bitmaps.
//!
//! For now we can use a grenad sorter for spilling even thought I think
//! it's not the most efficient way (too many files open, sorting entries).
