Release version 13.10.2 (#1647)

Bug fixes:

• Dart: introduced GLUECODIUM_DART_DISABLE_FINALIZABLE_MARKER variable as well as -dartdisablefinalizablemarker CLI flag, which allows conditionally disabling the usage of Finalizable interface from Dart:FFI. It was needed, because the fix introduced in Gluecodium's release 13.10.1 in some rare cases could cause internal compiler issue in Dart SDK (solved in Dart SDK 3.6.0+). This flag is intended to ease the transition to Dart 3.6.0+.
• Dart: fixed a bug related to compilation error caused by usage of @PositionalDefaults and default value for a field that uses type, which does not provide const constructor.
• Dart: disabled generation of invalid_use_of_visible_for_testing_member warning from the generated code for a hierarchy of classes.
• Dart: removed generation of redundant import for constants declared with external types. The redundant import caused linter warnings.
• Dart: removed generation of redundant default clause in exhaustive switch-cases for enumerations. The redundant default caused linter warnings.
• Java: cleaned up the generated code: removed blank lines.
