Port demos with remade art assets to Godot 4 (#922)

This re-ports the following demos to Godot 4 following their latest `3.x` versions:

- 2D Navigation with AStarGrid2D
- 2D JRPG Demo
- 2D Isometric Game
- 2D Platformer

Some tweaks have also been made in the process, such as split screen players
having different colors in the 2D Platformer demo.
