[renderjs_ui] Create new public method `updateForm` rather than misusing `displayFormulatorValidationError`.

In commit 89a17f04, disabling password
verification when passing an empty password was a bad idea, since it
wasn't possible to check fully the login form itself. Some tests broke
because of this change.

There was also a stupid mistake: `pw_validate` could call itself
instead of the original function.

--zope option was removed: it was an alias to
--generated-members=REQUEST,acl_users,aq_parent
but we anyway disable E1101.

This is consistent with packing_list_workflow

Reuse the one provided by erp5_xhtml_style

Only CKEditor and CodeMirror are still supported.
This will ensure the compatibility between erp5_xhtml_style and erp5_web_renderjs_ui.

This will improve the compatibility for all existing editorfield which will be migrated to gadgetfield (via proxy).

This allows to propagate more options to the render parameters, used in erp5_xhtml_style and erp5_web_renderjs_ui

But chrome is now unhappy...

GadgetField doesn't know how to validate/store REQUEST form data.
Use an external field to handle this task.
The external field must be located in the same form, and can be put in the hidden group if not rendered.

Add a test with a stringfield and a textarea field as validator.

Make ckeditor responsive.
Disable ACF.
