Axmol v3

Axmol v3: the biggest update so far

General

Now Axmol is C++23 standard

We know a lot of users choose Axmol because it's a C++ game engine, and they are passionate with the language. With the transition of Cocos2d-x to Axmol, C++ version was updated from 11 to 20, and now with the new Axmol v3 we give it a new bump up, to C++23.

Now Axmol supports D3D11, D3D12 and Vulkan

Together with OpenGL and Metal, Axmol v3 adds three more RHI (Render Hardware Interface) to the list: DirectX 11, DirectX 12 and Vulkan. This brings performance improvements around 55% compared with OpenGL (used by Cocos2d-x v4.0), and a 17% versus ANGLE, available in both Axmol v2 and Axmol v3. More info about the performance tests and how to switch between RHIs in this wiki page.

Added Dynamic RHI

As a true multiplatform game engine, having a Dynamic RHI who chooses the best RHI for each device was a very important goal of this update. More info in this PR - 3008.
