[Gradle] Restore Kapt import compatibility with older Kotlin plugin releases

Still supported IDEA/Kotlin plugin releases relies on
'kotlin-annotation-processing-gradle' artifact name in compiler plugins
classpath. I've restored this publication usage until we will stop
support Kotlin plugin versions that doesn't know about
'kotlin-annotation-processing-embeddable' name.
