OpenGL 4.6 Support

[mario-deluna]

This Branch serves as a starting point for OpenGL 4.6 Support.

I initially went with 4.1 because I wanted to keep MacOS fully compatible.

Before this can be merged, some mechanisms need to be integrated to properly check for compatibility.
Also a lot of functions are not properly mapped / ported on this branch which has to be fixed before we even consider merging this to master.

Building this on Mac currently fails for me with two errors:

[...]
