Add support for Kotlin inline classes [DATACMNS-1517]

See original GitHub issue

Wyatt Smith opened DATACMNS-1517 and commented

Here is an example with the bug: https://github.com/wyattjsmith1/SpringDataBug

When this runs, there is an IndexOutOfBoundsException. This is caused by kotlin’s synthetic constructor. I believe the issues is that synthetic constructors aren’t filtered before.

buildPreferredConstructor at org.springframework.data.mapping.model.PreferredConstructorDiscoverer.Discoverers#discover, but there is probably a better solution to this.

Changing AccountId in the data class to a String causes the application to work properly. Admittedly, inline classes are still experimental for Kotlin, but this might be worth investigating

Answered my own question, thanks to https://github.com/spring-projects/spring-data-commons/issues/2215#issuecomment-752410346. I was using unsigned types. Changing them to Int made the issue go away.
