Move LuxCoreRender to C++20

[howetuft]

Overview

This proposal aims to introduce the C++20 standard for building LuxCoreRender.

Rationale

In the C++20 standard, many functionalities previously supported by external dependencies are integrated into the standard library. These include:

• boost.atomic
• boost.thread
• boost.chrono
• boost.regex
• {fmt}
• etc.

In the future, this will help to lighten LuxCoreRender's external dependencies and, potentially, reduce the size of binaries.

Sounds like a reasonable goal to me!

@howetuft Could I ask you for a status update on this topic?
Do you have an overview what parts of the code still can be converted (if it makes sense to explicitly list them)?
