RemoveImport should look through supertypes for Kotlin

[jevanlingen]

What's changed?

The remove import recipe takes imports of super types into account.

What's your motivation?

Kotlin can import a static java member of a parent class by importing the child class. The recipe did not take this feature into account. There's also the option of using imports of companion objects with an interface. These kind of setup was not supported as well.

Any additional context

At the moment I could not find a proper way to add Java source code as dependency of the Kotlin sources, so I added a @Disabled test. If there's a way to do this, it should be used.

Checklist

• I've added unit tests to cover both positive and negative cases
• I've read and applied the recipe conventions and best practices
• I've used the IntelliJ IDEA auto-formatter on affected files
