Fix: remove duplicate test mutex lock; add Object.getOwnPropertyDescriptors and Symbol test updates
- Remove duplicate mutex acquisition in tests/symbol_additional_tests.rs to avoid deadlock - Implement Object.getOwnPropertyDescriptors with symbol and accessor support in src/js_object.rs - Add boolean branches for equality checks in src/core.rs to correct boolean comparisons - Update/add symbol-related tests and debug helper
