Add AnimatorListener extensions for easy kotlin usage

These extension functions already exist in core-ktx: https://source.corp.google.com/aosp-androidx/core/core-ktx/src/main/java/androidx/core/animation/Animator.kt

Those unfortunately do not support androidx.core.Animator but only android.animation.Animator.
