Following the new editor's merge at https://github.com/odoo/odoo/pull/29775
web_editor.base has been moved to website while it was still used by
frontend pages which do not depend on website (especially portal).
This commit moves web_editor.base to portal while waiting for
https://github.com/odoo/odoo/pull/29442. It also removes the unnecessary
dependencies to it in non-portal pages (in survey for example).
