[imgui-sfml] Add new port (#7429)

* [imgui-sfml] Add new package ImGui-SFML

* Static build only to match with `imgui`.

* [imgui-sfml] Fix case-sensitive imgui package name

* [imgui-sfml] Require C++11

* [imgui-sfml] Include IMGUI_API define

* [imgui-sfml] Remove delegating ctor - C++11 is not required
