- IR plugin does not use it anymore, regular annotation instantiation feature is used (insertion of IrConstructorCall(annotationCtorSymbol)). - IR plugin still generates `SerialInfo$Impl` class to be compatible with previously compiled code & libraries. - Custom implementation over descriptors in IR plugin is removed; plugin now delegates to the existing lowering with some tweaks. - $Impl descriptor is removed from FE 1.0 because it is no longer needed for IR plugin; it shouldn't be exposed to users so FIR doesn't need it either. - Since language lowering is now used, it is possible to correctly instantiate SerialInfo annotations with default values even if they are from other modules and even if they were not processed by the plugin. #KT-48733 Fixed Fixes https://github.com/Kotlin/kotlinx.serialization/issues/1574
