Merge #2414

2414: Improve index uid validation upon API key creation r=Kerollmops a=pierre-l

- ~Use an IndexUid newtype to enforce stronger constraints~
- ~`cargo update -p vergen`~ (`rustup update` was the proper fix for this)
- Add a new `meilisearch_types` crate
- Move `meilisearch_error` to `meilisearch_types::error`
- Move `meilisearch_lib::index_resolver::IndexUid` to `meilisearch_types::index_uid`
- Add a new `InvalidIndexUid` error in `meilisearch_types::index_uid`
- Move `meilisearch_http::routes::StarOr` to `meilisearch_types::star_or`
- Use the `IndexUid` and `StarOr` in `meilisearch_auth::Key`

Fixes #2158
