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).

* Remove unreachable code
* Add `indices` field to `MatchBounds`
For matches inside arrays, this field holds the indices of the array
elements that matched. For example, searching for `cat` inside
`{ "a": ["dog", "cat", "fox"] }` would return `indices: [1]`. For nested
arrays, this contains multiple indices, starting with the one for the
top-most array. For matches in fields without arrays, `indices` is not
serialized (does not exist) to save space.
5044: Adds new metrics to prometheus r=irevoire a=PedroTurik
not 100% confident in this solution, especially because i couldn't make the "Search Queue searches waiting" metric give me any value other than 0 with my local testing 😆. But i believe it solves the Issue.

# Pull Request
## Related issue
Parts of https://github.com/meilisearch/meilisearch/issues/4978
## What does this PR do?
- Move the code around the offline upgrade to its own module with a file per version
- Fix the upgrade from v1.9 to v1.10 because I couldn’t make it work anymore. It now uses a specified format instead of relying on cargo to get the right set of feature
- ☝️ must be checked against docker
- Provide an update path from v1.10 to v1.11. Most of the code is boilerplate in meilitool, the real code is located here: 053807bf38/src/lib.rs (L161-L269)
