fix: 修复 QuickJS test262 缺失 esnext/harness 文件导致跑失败

- 问题: QuickJS run-test262 要求 test262/harness/testBigIntTypedArray.js，但该文件实际在 test/esnext/harness/ 下
- 修复: bench_test262_qjs() 在跑 run-test262 前，自动把 tests/test262/test/esnext/harness/*.js 链接/拷贝到 baseline-quickjs/test262/harness/
- 影响: QuickJS baseline 跑完整个 test262 suite，不再中途挂死
