Fix duplicated class files in jar for JVM-only projects (#303)
Jar task for JVM-only projects packed both original and transformed classes with Kotlin 1.8.20 and Gradle 7.3. This commit contains fix for the issue, plus some refactoring in AtomicfuGradlePlugin using KGP API introduced in 1.7.0. * Fixed configuration of outputs classesDir: remove outputs of Kotlin compilation task and replace with atomicfu transformation task output * Refactoring: - Renamed the directory with original classes to `classes/atomicfu-orig/` - Introduced 'destinationDirectory' for AtomicFUTransformTask - Lazy registration of AtomicFU transform tasks * Added minimal supported version of KGP and Gradle (KGP >= 1.7.0, Gradle >= 7.0)
