[Configuration] Add Applets Tab to Per-Game Configurations (#3623)

Some games need specific applets to work.

For example for local multiplayer to function the Controller Applet must be set as:
- MK8D -> Custom Applet
- Absolum -> Real Applet

Web/Offline Applet: Assasin Creed and some bundled games might need real applet.

Overlay Toggle added for Horizon's ingame menu.

Thanks PavelBARABANOV for the help with the PR.
