This patch implements the creation, buffer-to-texture copies and
texture-to-texture copies with BC formats on OpenGL backend. Note that
OpenGL SPEC also has the same issue about texture-to-texture copies
with compressed textures as Vulkan SPEC, so we have to skip the related
case.
The texture-to-buffer copies with BC formats and related end2end tests
will be supported in the following patches.

This completely removes the dependency on glad by generating the GL
headers from gl.xml directly.
This requires adding khrplatform.h so all Khronos dependencies are
gathered in third_party/khronos.
Also removes a stray CMakeLists.txt that was still hanging out.

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.
