doc: Build a top-level index of the manuals.

Suggested by Julien Lepiller.

* doc/build.scm (html-manual-indexes)[build]: Add 'with-extensions'.
(translate): Actually honor DOMAIN.  Add call to 'bindtextdomain' for
ISO-CODES.
(%iso639-languages): New variable.
(language-code->name, top-level-index): New procedures.
Add call to 'write-html' for OUTPUT/index.html.
