【关键节点】修复D3D12CommandQueue::ExecuteCommandLists类型混淆bug并完善集成测试配置

1. D3D12CommandQueue::ExecuteCommandLists修复：确保正确调用GetNativeHandle()
2. 集成测试修复：传递&gCommandList而不是gCommandList.GetCommandList()
3. CMakeLists.txt修复：添加renderdoc.dll到所有D3D12/OpenGL集成测试的POST_BUILD命令

测试验证：
- 单元测试：144/144通过
- D3D12集成测试：minimal/quad/triangle/sphere全部通过
- OpenGL集成测试：minimal/quad/triangle/sphere全部通过
