Upgrade to Kotlin 1.5

Browse Source 
* To align with the rest of Spring portfolio, based on Spring Framework 5.3.x generation,
it is better to upgrade to the Kotlin version supported by SF
* Fix  `ClassUtils.isLambda()` to treat `$inlined$` classes as Kotlin lambdas and let
Java DSL to delegate to the `LambdaMessageProcessor` for better expected type handling.
Looks like Kotlin does not carry type info in its lambdas anymore (at least for functions).
* Add `-parameters` to the compiler args for possible method argument names discovery.
Essentially realign with the rest of portfolio
* Fix Kotlin tests for deprecated API
