Move autocomplete feature to a submodule

Locally test are passing for me, but for whatever reason they are not here, so setting the status to needs work.

The custom suggester did not make sense for what meili provides and what is already implemented. But because not all users will want to enable autocomplete, moving it to a sub-module was the only viable option, because of the dependency to search_api_autocomplete (now it's only needed if you want to enable the search_api_meilisearch_autocomplete module.)
Ready for review.

Tests are passing, it correctly works with full-text searches. I think this can be merged. Moving it to RTBC.

After trying to uninstall the module. I got the next error:

Fatal error: Trait "Drupal\search_api_meilisearch_autocomplete\BackendTrait" not found in /var/www/html/web/modules/custom/search_api_meilisearch-3386267/src/Plugin/search_api/backend/SearchApiMeilisearchBackend.php on line 39

Ready for review again.

The module still works, tests pass and now I can uninstall the module. Switching to RTBC.

Rebased, cleaned up the code and used query limit from settings.

Needs a test for when autocomplete settings has a min/max limit set to make sure this works properly.

Added the limit option to the test, ready for review.

The tests are still passing both here and locally. Just in case made sure the submodule still works. Setting it to RTBC.

Merged, thanks.

I've added an "Autocomplete" option to the "Component" dropdown so any issues regarding autocomplete submodule can use that option.
