Context: dotnet/android#4661 In 439bd83, we made a change to hide Kotlin `internal` members as we shouldn't be binding them. However a `public class` can inherit from an `internal interface`, so we need to emit those interfaces. Instead, emit `internal interface` types as "package private" types; `visibility=""` in `api.xml` parlance. This allows us to resolve the `interface` and thus successfully bind the `class`. In C#-land, the `interface` is not actually bound and the C# class doesn't actually implement it. This has no effect to the public API end user, who shouldn't be seeing the `internal interface` anyways. If a user really wants to publicly expose the `interface`, its `visibility` can be changed via `metadata`. ***Note***: Changing the `visibility` of a type may result in subsequent Java Callable Wrapper generation errors, if/when a Java Callable Wrapper attempts to implement the package-private type.
