add Koltin/Native

Hello ! Kotlin/Native is beta for Now but it have great future, with Kotlinx Serialization i think it must have great performance in Json Benchmark

I wouldn't agree on the "great" performance since the JVM target is generally faster due to the maturity and the amount of work put into it. Also, performance is not currently the number one priority for Kotlin/Native, but it's definitely going to be improved in future. Apart from that, I'd love to see Kotlin/Native in the benchmarks too!
