[atomicfu-K/N]: Support Native backend in atomicfu compiler plugin

Atomicfu compiler plugin supported transformations for K/N:
* atomic properties are replaced with volatile properties and all the operations are delegated to native atomic intrinsics
* atomic arrays are replaced with kotlin.concurrent.Atomic*Arrays
* all other features available on JVM are covered as well (custom atomic extensions, delegated properties, debug tracing)

See (KT-58358, https://github.com/Kotlin/kotlinx-atomicfu/issues/261)
