qt: Replace deprecated stateChanged with checkStateChanged

Updates QCheckBox signal connections to use checkStateChanged instead of
the deprecated stateChanged signal. This change affects:

- qt_controller.cpp
- configure_filesystem.cpp
- configure_input.cpp
- configure_input_advanced.cpp
- configure_system.cpp
- configure_ui.cpp
- shared_widget.cpp

Also updates lambda signatures to use Qt::CheckState instead of int for
the state parameter where needed.
