GPU Driven renderer design for Godot 4.x

Goals:

The main goal is to implement a GPU driven renderer for Godot 4.x. This is a renderer that happens entirely on GPU (no CPU Dispatches during opaque pass).

Additionally, this is a renderer that relies exclusively on raytracing (and a base raster pass aided by raytracing).

It is important to make a note that we dont want to implement a GPU driven renderer similar to that of AAA/Unreal, as example.
