Give typed access to configuration depending on the platform

[gzoritchak]

A configuration may have some generic parameters that apply on all platform and some that only make sense on a specific platform. It should be possible to provide access to these parameters using the same API but having different params depending on the platform.

viz {
    configure { // on common code
          resizable = false
    }
}

viz {
    configure { // on android
          minimumBatteryMinimumForAnimations = 40.pct
    }
}
