Atomicfu JVM IR compiler plugin does not remove atomicfu references from Metadata

[mvicsokolova]

JVM IR compiler plugin, introduced since Kotlin 1.7.20 leaves atomicfu references in metadata.
Example of metadata of the transformed class:

private final class kotlinx/coroutines/AwaitAll<T#0> : kotlin/Any {
  // field: deferreds:[Lkotlinx/coroutines/Deferred;
  private final val deferreds: kotlin/Array<out kotlinx/coroutines/Deferred<T#0>>
    private final get

  private final val notCompletedCount: kotlinx/atomicfu/AtomicInt          // <------ !!!
    private final get

  .....
}

Probably JVM IR compiler plugin removes the backingField of the atomic property but leaves the property itself.

Not critical, should be fixed on the compiler plugin side.
