636: Remove unused `infos`, `http-ui`, and `milli/fuzz`, crates r=ManyTheFish a=loiclec
We haven't used the `infos/`, `http-ui/` and `milli/fuzz/` crates in a long time. They are not properly maintained and probably do not work correctly anymore.
This PR removes these crates entirely from the workspace to reduce the amount of code we need to maintain.

635: Use an unstable algorithm for `grenad::Sorter` when possible r=Kerollmops a=loiclec
# Pull Request
## What does this PR do?
Use an unstable algorithm to sort the internal vector used by `grenad::Sorter` whenever possible to speed up indexing.
In practice, every time the merge function creates a `RoaringBitmap`, we use an unstable sort. For every other merge function, such as `keep_first`, `keep_last`, etc., a stable sort is used.

598: Matching query terms policy r=Kerollmops a=ManyTheFish
## Summary
Implement several optional words strategy.
## Content
Replace `optional_words` boolean with an enum containing several term matching strategies:
```rust
pub enum TermsMatchingStrategy {
// remove last word first
Last,
// remove first word first
First,
// remove more frequent word first
Frequency,
// remove smallest word first
Size,
// only one of the word is mandatory
Any,
// all words are mandatory
All,
}
```
All strategies implemented during the prototype are kept, but only `Last` and `All` will be published by Meilisearch in the `v0.29.0` release.
