[Android] Abstract serialiser

Currently the android library uses Jackson as a serialisation library. This makes Jackson a transitive dependency that lands in the consumers dependency tree.

My proposal would be to adapt a more agnostic approach and create an abstraction layer like a Converter (similar to the one in https://github.com/square/retrofit) and allow consumers to select different types of implementations via different artefacts.
There are at least 3 popular libraries used in Android development, so at lest does can be added as standalone artefacts:
- `native-navigation-converter-gson` for [Gson](https://github.com/google/gson)
- `native-navigation-converter-moshi` for [Moshi](https://github.com/square/moshi/)
- `native-navigation-converter-jackson` forJackson.

Start by reviewing the Android library's current Jackson integration and compare the proposed abstraction with Retrofit's Converter approach. Done means consumers can choose separate Gson, Moshi, or Jackson converter artefacts without Jackson becoming a transitive dependency.
