Can `FirSupertypeGenerationExtension` add super classes, i.e. not interfaces?  I'm adding a superclass, which results in FIR that looks like `class TestModule : R|kotlin/Any|, R|dev/rnett/lattice/module/BaseModule|`, IR `CLASS CLASS name:TestModule modality:FINAL visibility:public superTypes:[kotlin.Any; dev.rnett.lattice.module.BaseModule]`, and the JVM bytecode `class test/basic/TestModule {`, with only `Object` as the supertype.  I could probably do some massaging in the IR to remove `Any` but that seems pretty hacky

I am able to extend an interface, and implement it in FIR/IR. <https://github.com/nomisRev/ktor-typed/blob/main/compiler-plugin/src/io/github/nomisrev/typedapi/compiler/plugin/fir/AddSupertypeExtension.kt|https://github.com/nomisRev/ktor-typed/blob/main/compiler-plugin/src/io/github/nomisrev/typedapi/compiler/plugin/fir/AddSupertypeExtension.kt>

Worked in 2.1.20, and 2.2.0

Yeah, I would expect an interface to work.  But I'm trying to add a superclass that's an abstract class, and it's not working.  I'm guessing because it still gets `Any`
