[AA decompiler] Store sealed modifiers in interface stubs

- If the `sealed` modifier is not kept in the interface's stub, a
  sealed interface will have an `abstract` modality instead, which
  causes issues with `when` exhaustiveness analysis in K2.
- This issue also affected K1, but it was less visible there because
  `when` exhaustiveness analysis in K1 uses deserialized descriptors.
