This is the companion PR of godotengine/godot#99986.
Do not merge until the main PR is merged.

I didn't find any section of the documentation that would become obsolete or require major additions whenever godot gets support for rendering with very large z-far.

However I found useful to suggest a handful of enhancements that clarify the links between z-buffer, large world coordinates, and large z-far.

As a side note, I realized that it may also be more consistent to move page _doc_large_world_coordinates to 3D section (it's now in Physics). Large world coordinates are more general than just physics as they also concern rendering. Happy to discuss this point too and update this PR if needed.
