600: Simplify some unit tests r=ManyTheFish a=loiclec
# Pull Request
## What does this PR do?
Simplify the code that is used in unit tests to create and modify an index. Basically, the following code:
```rust
let path = tempfile::tempdir().unwrap();
let mut options = EnvOpenOptions::new();
options.map_size(10 * 1024 * 1024); // 10 MB
let index = Index::new(options, &path).unwrap();
let mut wtxn = index.write_txn().unwrap();
let content = documents!([
{ "id": 0, "name": "kevin" },
]);
let config = IndexerConfig::default();
let indexing_config = IndexDocumentsConfig::default();
let builder =
IndexDocuments::new(&mut wtxn, &index, &config, indexing_config, |_| ()).unwrap();
let (builder, user_error) = builder.add_documents(content).unwrap();
user_error.unwrap();
builder.execute().unwrap();
wtxn.commit.unwrap();
let mut wtxn = index.write_txn().unwrap();
let config = IndexerConfig::default();
let mut builder = Settings::new(&mut wtxn, &index, &config);
builder.set_primary_key(S("docid"));
builder.set_filterable_fields(hashset! { S("label") });
builder.execute(|_| ()).unwrap();
wtxn.commit().unwrap();
```
becomes:
```rust
let index = TempIndex::new():
index.add_documents(documents!(
{ "id": 0, "name": "kevin" },
)).unwrap();
index.update_settings(|settings| {
settings.set_primary_key(S("docid"));
settings.set_filterable_fields(hashset! { S("label") });
}).unwrap();
```
Then there is a bunch of options to modify the indexing configs, the map size, to reuse a transaction, etc. For example:
```rust
let mut index = TempIndex::new_with_map_size(1000 * 4096 * 10);
index.index_documents_config.autogenerate_docids = true;
let mut wtxn = index.write_txn().unwrap();
index.update_settings_using_wtxn(&mut wtxn, |settings| {
settings.set_primary_key(S("docids"));
}).unwrap();
wtxn.commit().unwrap();
```

556: Add EXISTS filter r=loiclec a=loiclec
## What does this PR do?
Fixes issue [#2484](https://github.com/meilisearch/meilisearch/issues/2484) in the meilisearch repo.
It creates a `field EXISTS` filter which selects all documents containing the `field` key.
For example, with the following documents:
```json
[{
"id": 0,
"colour": []
},
{
"id": 1,
"colour": ["blue", "green"]
},
{
"id": 2,
"colour": 145238
},
{
"id": 3,
"colour": null
},
{
"id": 4,
"colour": {
"green": []
}
},
{
"id": 5,
"colour": {}
},
{
"id": 6
}]
```
Then the filter `colour EXISTS` selects the ids `[0, 1, 2, 3, 4, 5]`. The filter `colour NOT EXISTS` selects `[6]`.
## Details
There is a new database named `facet-id-exists-docids`. Its keys are field ids and its values are bitmaps of all the document ids where the corresponding field exists.
To create this database, the indexing part of milli had to be adapted. The implementation there is basically copy/pasted from the code handling the `facet-id-f64-docids` database, with appropriate modifications in place.
There was an issue involving the flattening of documents during (re)indexing. Previously, the following JSON:
```json
{
"id": 0,
"colour": [],
"size": {}
}
```
would be flattened to:
```json
{
"id": 0
}
```
prior to being given to the extraction pipeline.
This transformation would lose the information that is needed to populate the `facet-id-exists-docids` database. Therefore, I have also changed the implementation of the `flatten-serde-json` crate. Now, as it traverses the Json, it keeps track of which key was encountered. Then, at the end, if a previously encountered key is not present in the flattened object, it adds that key to the object with an empty array as value. For example:
```json
{
"id": 0,
"colour": {
"green": [],
"blue": 1
},
"size": {}
}
```
becomes
```json
{
"id": 0,
"colour": [],
"colour.green": [],
"colour.blue": 1,
"size": []
}
```

This bug is an old bug but was hidden by the proximity criterion,
Phrase search were always returning an empty candidates list.
Before the fix, we were trying to find any words[n] near words[n]
instead of finding any words[n] near words[n+1], for example:
for a phrase search '"Hello world"' we were searching for "hello" near "hello" first, instead of "hello" near "world".
