Fix some unresolved supertypes. This is necessary to be able to enable IR fake override builder by default (KT-61514), because it traverses all supertypes and asserts that they're classes, so that it can build fake overrides for declarations from there. Without this change, for example `IrFakeOverrideBuilder.buildFakeOverridesForClass` would crash.
