David 'Digit' Turner 5dee3e826b [generator_lib]: Make generator_lib.py easier to reuse.
This CL tries to make generator_lib.py easier to reuse in
other projects (e.g. non Dawn-related), by doing the following:

- Removing dawn-specific variables from the script and
  replacing them by path-relative defaults, or through
  additional command-line parameters (e.g. --root-dir can
  now be used to pass the root source directory for Python
  dependency computations).

- Move project-agnostic processing from dawn_generator
  GN template into a new generator_lib:generator_lib_action
  template. The new generator_lib.gni file does not
  contain Dawn-specific settings and can be reused more
  easily outside of Dawn.

+ Replace --extra-python-path with --jinja2-path to be
  more explicit.

+ Add a few documentation comments in the Python scripts.

Corentin Wallez df69f24824 OpenGL: Don't use glad to load OpenGL entrypoints
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.

Corentin Wallez 031fbbbaa1 Generators: main.py is now dawn_json_generator.py
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

Corentin Wallez 0c38e92187 Split off the reusable part of the code generator
This is in preparation for using it to generate code for replacing glad
with our own OpenGL function pointer loading code.
