gl-renderer: move extension lists away from log

Print all EGL and OpenGL extension lists into a new log scope
"gl-renderer" instead of the usual log.

These lists cluttered the log while they were very rarely actually
useful. Sometimes they might be interesting, so make them still
available through the new log scope.
