Replace NativeWrapper with proper native interface

[hvge]

In the current implementation, we perform all calls to the native PowerAuth module with using parameter unsafe construct that get function name and array with parameters at its input. We should replace this with a more robust solution based on a typescript interface.

We're already doing this for PowerAuthPassword and PowerAuthPassphraseMeter classes.

This is low priority task, we can live with the current implementation, but it would be nice to have a full type-safe interface to our primary native module.
