483: Enhance matching words r=Kerollmops a=ManyTheFish

# Summary

Enhance milli word-matcher making it handle match computing and cropping.

# Implementation

## Computing best matches for cropping

Before we were considering that the first match of the attribute was the best one, this was accurate when only one word was searched but was missing the target when more than one word was searched.

Now we are searching for the best matches interval to crop around, the chosen interval is the one:
1) that have the highest count of unique matches
> for example, if we have a query `split the world`, then the interval `the split the split the` has 5 matches but only 2 unique matches (1 for `split` and 1 for `the`) where the interval `split of the world` has 3 matches and 3 unique matches. So the interval `split of the world` is considered better.
2) that have the minimum distance between matches
> for example, if we have a query `split the world`, then the interval `split of the world` has a distance of 3 (2 between `split` and `the`, and 1 between `the` and `world`) where the interval `split the world` has a distance of 2. So the interval `split the world` is considered better.
3) that have the highest count of ordered matches
> for example, if we have a query `split the world`, then the interval `the world split` has 2 ordered words where the interval `split the world` has 3. So the interval `split the world` is considered better.

## Cropping around the best matches interval

Before we were cropping around the interval without checking the context.

Now we are cropping around words in the same context as matching words.
This means that we will keep words that are farther from the matching words but are in the same phrase, than words that are nearer but separated by a dot.

> For instance, for the matching word `Split` the text:
`Natalie risk her future. Split The World is a book written by Emily Henry. I never read it.`
will be cropped like:
`…. Split The World is a book written by Emily Henry. …`
and  not like:
`Natalie risk her future. Split The World is a book …`

493: Use smartstring to store the external id in our hashmap r=Kerollmops a=irevoire

We need to store all the external id (primary key) in a hashmap
associated to their internal id.
The smartstring remove heap allocation / memory usage and should
improve the cache locality.

I ran the benchmarks to measure the impact of this PR on the indexing time.
I think we should merge it whatever happens thought because it'll decrease the memory consumption.

---------

This improve really sliiiiiightly the performances but improve the memory usage thus it should be merged.

496: Improve the performances of the flattening subcrate r=irevoire a=Kerollmops

This PR adds some benchmarks to the _flatten-serde-json_ crate, this crate is responsible for transforming the original documents into flat versions that the engine can understand. It can probably be speed-up and this is why I added benchmarks to it.

I make some interesting performance improvements when I replaced the `json!` macro calls.

```
flatten/simple          time:   [452.44 ns 453.31 ns 454.18 ns]
                        change: [-15.036% -14.751% -14.473%] (p = 0.00 < 0.05)
                        Performance has improved.
Found 2 outliers among 100 measurements (2.00%)
  2 (2.00%) high mild

                        change: [-18.001% -17.775% -17.536%] (p = 0.00 < 0.05)
                        Performance has improved.
Found 6 outliers among 100 measurements (6.00%)
  5 (5.00%) high mild
  1 (1.00%) high severe
```

---

_I removed this particular commit from this PR._ The reason is that the two other commits were enough for this PR to give enough impact and be merged. We will continue to explore where we can get performances later.

But when I changed the flattening function to accept an owned version of the objects, we lost a lot of performances. Yes, I rewrote the benchmarks (locally) to clone the input object (and measured both, previous and new versions, with the cloning benchmarks). Maybe cloning the benchmark inputs is not the right thing to do...

```

489: fix distinct count bug r=curquiza a=MarinPostma

fix https://github.com/meilisearch/meilisearch/issues/2152

I think the issue was that we didn't take off the excluded candidates from the initial candidates when returning the candidates with the search result.

- Adapt the release drafter to these new labels
- rename `skip-changelog` into `skip changelog` according to the new label name

458: Nested fields r=Kerollmops a=irevoire

For the following document:
```json
{
  "id": 1,
  "person": {
    "name": "tamo",
    "age": 25,
  }
}
```
Suppose the user sets `person` as a filterable attribute. We need to store `person` in the filterable _obviously_. But we also need to keep track of `person.name` and `person.age` somewhere.
That’s where I changed a little bit the logic of the engine.

Currently, we have a function called `faceted_field` that returns the union of the filterable and sortable.
I renamed this function in `user_defined_faceted_field`. And now, when we finish indexing documents, we look at all the fields and see if they « match » a `user_defined_faceted_field`.
So in our case:
- does `id` match `person`: 🔴 
- does `person.name` match `person`: 🟢 
- does `person.age` match `person`: 🟢 

And thus, we insert in the database the following faceted fields: `person, person.name, person.age`.

The good thing about that solution is that we generate everything during the indexing phase, and then during the search, we can access our field without recomputing too much globbing.

-----

Now the bad thing is that I had to create a new db.

And if that was only one db, that would be ok, but actually, I need to do the same for the:
- Displayed attributes
- Attributes to retrieve
- Attributes to highlight
- Attribute to crop

`@Kerollmops` 
Do you think there is a better way to do it?
Apart from all the code, can we have a problem because we have too many dbs?
