#43590: Use robots meta tag to better discourage search engines.

This changes the "discourage search engines" option to output a noindex, nofollow robots meta tag. Disallow: / is removed from the robots.txt to allow search engines to discover they are requested not to index the site.

Disallowing search engines from accessing a site in the robots.txt file can result in search engines listing a site with a fragment (a listing without content).

Props donmhico, jonoaldersonwp.
Fixes #43590.
