Doc: Update CMake configuration info

- Initial variables are now listed in the Initial Configuration tab
  and current ones in the Current Configuration tab.
- CMake builds can be stopped.
- Variables are no longer grouped according to their prefix.
- Kit Configuration button enables setting CMake options for the
  current kit.
