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.

This merges all the files for main.py together again except
generator_lib.py because there doesn't seeem to be a good way to
separate the pure dawn.json generators and the dawn wire generator.
Also updates the GN templates to make it easier to define new generators
based on generator_lib, and move the Jinja2 template "stdlib" to
generator_lib.py

This is in preparation for using it to generate code for replacing glad
with our own OpenGL function pointer loading code.
