noscript fallback

[jnorell]

It would be nice to have fallback functionality on the frontend without javascript enabled.

Maybe start with always displaying the cookie banner if gdpr cookie isn't set, so it always displays if javascript is disabled and the "I Agree" button hasn't been clicked.

Then the 'Privacy Preferences' link (as well as gdpr_preferences shortcode button) and the 'I Agree' button would need a non-javascript fallback. For the preferences, just a single page that lists everything out in sections with enable checkbox should work, and both this preferences page and the I Agree button would then need to submit via POST rather than ajax as a fallback.

Thanks
