Update deconstructor(chain) in all projects

```cpp
DearImGuiApplication::~DearImGuiApplication()
{
...
Application::Cleanup();
}

Application::~Application()
{
Application::Cleanup();
}

void Application::Cleanup()
{
glfwDestroyWindow(_window);
glfwTerminate();
}
```

looks fishy

Start by locating DearImGuiApplication::~DearImGuiApplication, Application::~Application, and Application::Cleanup across the projects. Trace the destructor chain and the GLFW window and termination calls shown in the issue. Done means the cleanup ownership is unambiguous and resources are not cleaned up more than once in every affected project.
