Remove glad and replace it with our own GL header
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.
