Option to generate Bundle without Intent or Fragment

[cedrickcooke]

Use case here is easier integration into AndroidX Navigation (as an alternative to SafeArgs, since it's not supported when using the XML-free DSL).

@Exercise(Argument("foo", Int::class))
class DestinationFragment : Fragment() {
    // ...
}

class SourceFragment : Fragment() {
    fun navigateToDest() {
        findNavController().navigate(R.id.action, DestinationFragmentArgs(foo = 5))
    }
}

Not to assume the function name here.
