Early C++ implementation for the CompoundClouds' system

[AverageNerdz]

This PR introduces a basic implementation of the CompoundClouds system in C++. While it lays the groundwork for future development, there are several known issues and limitations that need to be addressed. Once these issues are resolved, this PR will close Issue #4917.

Related Issues:

• Color Overload Inside the Clouds: The cloud rendering exhibits excessive color variation leading to unrealistic appearances across the compounds even when they shouldn't be there.
• Basic Absorption System: The current absorption mechanics are rudimentary and require further refinement.
• Overgeneration of Textures: The texture generation process is inefficient leading to performance issues and potential visual clutter.
• Unoptimized Code: The implementation is not optimized, resulting in increased resource usage.
• Memory Leaks: There are potential memory leaks that need to be addressed to ensure stable performance.

This implementation serves as a starting point, and I look forward to refining it further with your feedback.

Benchmark Results

I'd also like to share benchmark results comparing the CS benchmark with the C++ implementation:
