LibGL: Generate the API wrappers We now generate all LibGL API wrappers from a single API method definition list stored in `GLAPI.json`. Since a significant portion of the OpenGL API methods are relatively consistent variants, we take advantage of this to generate a lot of these variants at once. The autogenerated methods check for the non-nullness of the current `GLContext`, and only perform an action if a `GLContext` is present. This prevents a crash in ports like GLTron, who assume you can still call the OpenGL API without an active context. This increases our API wrapper method count from 211 to 356.
