This publication creates one variant for each native platform. 
It allows depending (and exposing) a single dependency, which can later
be resolved to platform-specific artifacts.

Simple example usage:
```kotlin
kotlin {
    target.attributes {
        attribute(ARCHITECTURE_ATTRIBUTE, objects.named(DefaultNativePlatform.getCurrentArchitecture().name))
        attribute(OPERATING_SYSTEM_ATTRIBUTE, objects.named(DefaultNativePlatform.getCurrentOperatingSystem().toFamilyName()))
    }
}

dependencies {
    implementation("org.jetbrains.skiko:skiko-awt:1.0-SNAPSHOT")
    implementation("org.jetbrains.skiko:skiko-awt-runtime:1.0-SNAPSHOT")
}
```

## Motivation
This allows 'intermediate' libraries to express that this dependency
exists (in a single publication) and push down the artifact selection to
consumers. This is an advanced feature and can be leveraged by more
complex builds.
