Unfortunately, there is only one G clef in LilyPond at a time, so it is not
possible to use LilyPond to display both clefs in one file.  The only images
I could find on the -devel list were not of the final clefs used.

You can compare two clefs side-by-side by creating two different scores and
using svg output.  Then you can copy one clef to the other document.

To find out things like that, you need to search the git repository (not
particularly helpful, I know, but that's how it's currently set up).

Go to 

http://git.savannah.gnu.org/gitweb/?p=lilypond.git

and search for clef.  There you'll see a commit by Marc Hohl, dated
2010-01-28, that says "Font: rotating the g clef for better appearance".
 (You also can see that it wasn't added to Changes until 2010-05-17).

Looking at the tags section of the git repository at Savannah, you can see
all of the 2.13.x releases.  2.13.12-1 is dated 4 Feb 2019; 2.13.11-1 is
dated 16 Jan 2010.

Therefore, the clef rotation was new with 2.13.12.

HTH,
