K1 uses `Any?` in `transformSuspendFunctionToRuntimeFunctionType`, so use `Any?` in K2 too. This type is not used for anything, it's just an artifact of how suspend types are represented in metadata. It's removed during deserialization (see `TypeDeserializer.createSuspendFunctionType` or `FirTypeDeserializer.createSuspendFunctionType`). So it's not a user-visible change. The only effect is that it reduces differences in metadata between K1 and K2, namely in the test `libraries/tools/kotlinp/testData/ValueClass.kt`.
