[3.x] Add a 2D version of the dynamic split screen demo (#762)

* add a 2D version of the dynamic split screen demo

* refactor the dynamic split screen demo

 - both 2D and 3D scenes have the exact same hierarchy
 - a single camera_controller.gd script instead of one per mode
 - the third viewport for 2D mode has been removed

+# Dodge the Creeps
+
+This is a simple game where your character must move
+and avoid the enemies for as long as possible.
+
+This is a finished version of the game featured in the
+["Your first 2D game"](https://docs.godotengine.org/en/latest/getting_started/first_2d_game/index.html)
+tutorial in the documentation. For more details,
+consider following the tutorial in the documentation.
+
+Language: GDScript
+
+Renderer: GLES 3 (particles are not available in GLES 2)
+
+Note: There is a C# version available [here](https://github.com/godotengine/godot-demo-projects/tree/master/mono/dodge_the_creeps).
+
+Note: There is a GDNative C++ version available [here](https://github.com/godotengine/gdnative-demos/tree/master/cpp/dodge_the_creeps).
+
+Check out this demo on the asset library: https://godotengine.org/asset-library/asset/515

+# Hierarchical Finite State Machine
+
+This example shows how to apply the State machine programming
+pattern in GDscript, including Hierarchical States, and a
+pushdown automaton.
+
+Language: GDScript
+
+Renderer: GLES 2
+
+Check out this demo on the asset library: https://godotengine.org/asset-library/asset/516
+
+## Why use a state machine
+
+States are common in games. You can use the pattern to:
+
+1. Separate each behavior and transitions between behaviors,
+   thus make scripts shorter and easier to manage.
+
+2. Respect the Single Responsibility Principle.
+   Each State object represents one action.
+
+3. Improve your code's structure. Look at the scene tree and
+   FileSystem tab: without looking at the code, you'll know
+   what the Player can or cannot do.
+
+You can read more about States in the excellent
+[Game Programming Patterns ebook](https://gameprogrammingpatterns.com/state.html).
