HHH-15707 - Fix Gradle plugin with Kotlin 1.7.0 or higher

Since Kotlin version 1.7.0 the KotlinCompile task no longer extends
Gradle's AbstractCompile.

This commit updates Hibernate Gradle enhancement plugin to not cast to
AbstractCompile and instead use reflection to invoke the
"getDestinationDirectory" method.

It also updates the Kotlin version on used to test the Gradle
enhancement (but remains backwards compatible with previous Kotlin
versions).
