feat: kotlinx serialization for GraphQLServerRequest -- cherry pick (#1937) (#1944)
Switch from `jackson` to `kotlinx.serialization` for serialization/deserialization of `GraphQLServerRequest` types. After running benchmarks we where able to identify that deserializing `GraphQLServerRequest` with `kotlinx.serialization` is quite faster than doing it with `jackson`, the reason ? possibly because jackson relies on reflections to identify deserialization process. On the other hand, serialization/deserialization of `GraphQLServerReponse` type is still faster if done with `jackson`, possibly because of how `kotlinx.serialization` library was designed and the poor support for serializing `Any` type: Kotlin/kotlinx.serialization#296, which causes a lot of memory comsumption. As part of this PR also including the benchmarks. For that, i created a separate set of types that are marked with both `jackson` and `kotlinx.serialization` annotations. Benchmarks results: Executed on a MacBookPro 2.6 GHz 6-Core Intel Core i7. `GraphQLBatchRequest` 4 batched operations, each operation is aprox: 30kb <img width="1260" alt="image" src="https://github.com/ExpediaGroup/graphql-kotlin/assets/6611331/06e5b218-a35e-4baa-a25e-2be1b3c27a95"> `GraphQLRequest` <img width="1231" alt="image" src="https://github.com/ExpediaGroup/graphql-kotlin/assets/6611331/e5ecba01-fd41-4872-b3e8-5519414cc918"> `GraphQLBatchResponse` <img width="1240" alt="image" src="https://github.com/ExpediaGroup/graphql-kotlin/assets/6611331/ee84bfa4-d7d1-46b4-b4a8-b3c220998a03"> `GraphQLResponse` <img width="1197" alt="image" src="https://github.com/ExpediaGroup/graphql-kotlin/assets/6611331/c217e05f-45fc-460e-a059-7667975ee49f"> ### 📝 Description ### 🔗 Related Issues
