Add OpenGL ES extension header to fetch enums from.

* There's a minor conflict over GL_ACTIVE_PROGRAM_EXT being defined to
  different values in GLES and GL extension headers. Since in the GL
  extension header it's defined to the value that eventually became
  GL_CURRENT_PROGRAM we remove that define.
