4633: Allow to mark vectors as "userProvided" r=Kerollmops a=dureuill

# Pull Request

## Related issue
Fixes #4606 

## What does this PR do?

[See usage in PRD](https://meilisearch.notion.site/v1-9-AI-search-changes-e90d6803eca8417aa70a1ac5d0225697#deb96fb0595947bda7d4a371100326eb)

- Extends the shape of the special `_vectors` field in documents.
    - previously, the `_vectors` field had to be an object, with each field the name of a configured embedder, and each value either `null`, an embedding (array of numbers), or an array of embeddings.
    - In this PR, the value of an embedder in the `_vectors` field can additionally be an object. The object has two fields:
      1. `embeddings`: `null`, an embedding (array of numbers), or an array of embeddings.
      2. `userProvided`: a boolean indicating if the vector was provided by the user.
    - The previous form `embedder_or_array_of_embedders` is semantically equivalent to:
    ```json
    {
        "embeddings": embedder_or_array_of_embedders,
        "userProvided": true
    }
    ```
- During the indexing step, the subfields and values of the `_vectors` field that have `userProvided` set to **false** are added in the vector DB, but not in the documents DB: that means that future modifications of the documents will trigger a regeneration of that particular vector using the document template.
- This allows **importing** embeddings as a one-shot process, while still retaining the ability to regenerate embeddings on document change.
- The dump process now uses this ability: it enriches the `_vectors` fields of documents with the embeddings that were autogenerated, marking them as not `userProvided`. This allows importing the vectors from a dump without regenerating them.

### Tests

This PR adds the following tests

- Long-needed hybrid search tests of a simple hf embedder
- Dump test that imports vectors. Due to the difficulty of actually importing a dump in tests, we just read the dump and check it contains the expected content.
- Tests in the index-scheduler: this tests that documents containing the same kind of instructions as in the dump indexes as expected

4644: Revert "Stream documents" and keep heed+arroy to the latest verion r=Kerollmops a=irevoire

Reverts meilisearch/meilisearch#4544

Fixes https://github.com/meilisearch/meilisearch/issues/4641

I didn’t realize that some http clients were not handling chunked http requests like you would expect (if you ask the body, it gives you the body), which made the previous PR breaking.

There is no way to provide a good fix to the issue we initially wanted to fix without breaking meilisearch and that’s not planned for now.

4631: Split the field id map from the weight of each fields r=Kerollmops a=irevoire

# Pull Request

## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/4484

## What does this PR do?
- Make the (internal) searchable fields database always contain the searchable fields (instead of None when the user-defined searchable fields were not defined)
- Introduce a new « fieldids_weights_map » that does the mapping between a fieldId and its Weight
- Ensure that when two searchable fields are swapped, the field ID map doesn't change anymore (and thus, doesn't re-index)
- Uses the weight instead of the order of the searchable fields in the attribute ranking rule at search time
- When no searchable attributes are defined, make all their weights equal to zero
- When a field is declared as searchable and contains nested fields, all its subfields share the same weight

## Impact on relevancy

### When no searchable attributes are declared

When no searchable attributes are declared, all the fields have the same importance instead of randomly giving more importance to the field we've encountered « the most early » in the life of the index.

This means that before this PR, send the following json:
```json
[
  { "id": 0, "name": "kefir", "color": "white" },
  { "id": 1, "name": "white", "last name": "spirit" }
]
```

Would make the field `name` more important than the field `color` or `last name`.
This means that searching for `white` would make the document `1` automatically higher ranked than the document `0`.

After this PR, all the fields have the same weight, and none are considered more important than others.

### When a nested field is made searchable

The second behavior change that happened with this PR is in the case you're sending this document, for example:

```json
{
  "id": 0,
  "name": "tamo",
  "doggo": {
    "name": "kefir",
    "surname": "le kef"
  },
  "catto": "gromez"
}
```

Previously, defining the searchable attributes as: `["tamo", "doggo", "catto"]` was actually defining the « real » searchable attributes in the engine as: `["tamo", "doggo", "catto", "doggo.name", "doggo.surname"]`, which means that `doggo.name` and `doggo.surname` were _NOT_ where the user expected them and had completely different weights than `doggo`.
In this PR all the weights have been unified, and the « real » searchable fields look like this:
```json
[ "tamo", "doggo", "doggo.name", "doggo.surname", "catto"]
   ^^^^    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^    ^^^^^
Weight 0                 Weight 1                  Weight 2
