Fixed issues with HMPP + AtomicFU version 0.14.3

* Use the atomicfu root MPP module dependency, 'atomicfu-native'
* Enable compatibility metadata variant publishing for consumers without HMPP
* Enable Gradle module metadata needed for HMPP to resolve dependencies properly
* Use AtomicFU version 0.14.3
