feat: gamepad support first version

[liana-p]

First version of the gamepad support. All the systems for it are working and in place.

• The inputs store can take a list of actions which can have keyboard or gamepad keybinds
• Components can register input events to it in a stack so that only the last one is active
• There is a useNavigation helper for list/grid interfaces to select them
• The game uses the first gamepad it finds as the main gamepad

Still to do:

• Plug the system in more parts of the engine. For now it's possible to interact only with the dialog box, and to open the menus and cycle their tabs
• Implement analog support (probably will be needed to control scroll wheels with right stick)
• Make the inputs configurable via yaml files (they're hardcoded for now)

I will release this soon though as it's already functional enough as it is, and an improvement on not having it at all.
