[WIP] Rework - Inputs management to include all gamepad mapping

[Greenlamp2]

Rework of the input handling, to allow different gamepad, not yet ready to be merged, still a WIP, everything is already working except the feature that let a key pressed and it's doing it repeatedly until we let it go.

It's food for @EmoUsedHM01 and @Flashfyre . I tried to do something readable and "clean" but i think it can be better. Let me know if i did something wrong, this is my first PR here, and hopefully not the last one.

Based on a discussion we had on discord, for the context:

(it's also fixing the issue of the C/Shift not working anymore when a gamepad is used.)

I've extracted all the input detection logic into an InputsController, but i've let the Ui logic based on inputs in the battle-scene.ts. Would you like me to takle that out too ?

For me, everything is okay, xbox controller, generic controller, keyboard and touch. Just need someone to test the dualschock controller.
