kcms/gamecontroller: Add switch for KWin "gamecontroller" plugin into KCM
Add the ability to enable/disable the new KWin "gamecontroller" plugin. The new UI element will be added as part of the existing gamecontroller KCM.
This plugin will:
- Allow game controllers to navigate the Plasma desktop (mouse/keyboard emulation)
- Automatically disable emulation when a game is using the controller
- Prevent system suspend while the controller is active
- Support hotplugging (connect/disconnect detection)
