This makes the OpenGL entry points loaded at Adapter creation from the getProcAddress passed in the DiscoveryOptions and update all GL calls in the backend to go through the new OpenGLFunctions object. A code generator is added that generates the function loader and list of GL procs from Khronos' gl.xml file but we can't get rid of glad yet because it is used to have the PROC typedefs and enum values.
