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).
