Remove experimental sync promo layouts

Remove experimental sync promo layouts

We added four experimental sync promo layouts for M18. The experiment is now over and we've decided to use layout 3 (simple version).

This CL removes the experimental layouts from the C++ code. I'll send out a second CL to remove the DOM UI code.
