reduz 70f5972905 Refactored Mesh internals and formats. 
-Changed how mesh data is organized, hoping to make it more efficient on Vulkan and GLES.
-Removed compression, it now always uses the most efficient format.
-Added support for custom arrays (up to 8 custom formats)
-Added support for 8 weights in skeleton data.
-Added a simple optional versioning system for imported assets, to reimport if binary is newer
-Fixes #43979 (I needed to test)

WARNING:

-NOT backwards compatible with previous 4.x-devel, will most likely never be, but it will force reimport scenes due to version change.
-NOT backwards compatible with 3.x scenes, this will be eventually re-added.
-Skeletons not working any longer, will fix in next PR.
