Support custom login pages

Browse source 
- Add the button (and error messages) to every wp_login_form() form via
  login_form_top/login_form_bottom; in button-only mode the password
  fields are wrapped and hidden there.
- New template functions m365_login_button() and m365_login_messages();
  the shortcode gains divider and messages attributes.
- New setting for the custom login page URL: failed sign-ins, the
  fallback link and the logout redirect point there instead of
  wp-login.php. Must be a same-site URL.
- Button-only mode now blocks every interactive password sign-in
  through the authenticate filter, not only wp-login.php; XML-RPC, REST,
  WP-CLI and cron are exempt, plus a filter for trusted exceptions.
- Fallback key accepted on any page (init) instead of login_init only.
