Update Kotlin to version 2.1.0

[andreas-eberle]

Update Kotlin to version 2.1.0, Kotlinx Serialization to 1.8.0 and Kotlin Coroutines to 1.10.0

Since the Kotlin update was removed again from PR #45228, I'm opening this PR to add it separately. This is an updated version of the original PR #44809.
