TCF CMP stub

[allisonking]

Closes N/A (an unexpected addition to #3813)

Description Of Changes

Adds a CMP stub that supports iframes. We need this for TCF certification (the chrome extension operates in an iframe). More info here: https://github.com/InteractiveAdvertisingBureau/GDPR-Transparency-and-Consent-Framework/blob/master/TCFv2/IAB%20Tech%20Lab%20-%20CMP%20API%20v2.md#how-can-scripts-on-a-page-determine-if-there-is-a-cmp-present

Code Changes

• Adapts the official stub library to TypeScript and changes its exports a little bit to make it easier to import
  • I was getting errors trying to import this in rollup since it didn't have a default export
• Calls the stub library

Steps to Confirm

• Run fides via nox -s dev
• Run the privacy center via FIDES_PRIVACY_CENTER__TCF_ENABLED=true turbo dev
• Make sure tcf is enabled in /consent-settings
• Install this chrome extension
• Activate the chrome extension on /fides-js-demo.html
• It should give you a handy report!

Pre-Merge Checklist

• All CI Pipelines Succeeded
• Update CHANGELOG.md
