Add reflection hints for Kotlin reflection on functions

Kotlin reflection API invocation on a specific function
may require iterating on all Java methods to find the right
Kotlin function. As a consequence, this commit adds introspection
hints on the class declared methods for all Kotlin beans since
the impact on the footprint is low.

Closes gh-29663
