TCF features and legal basis dropdown

[allisonking]

Closes #3940
Closes #3928

Description Of Changes

• Renders features and their description (it turns out the code to render features was already in place—just added a description)
• Adds a legal basis dropdown to both the Purposes tab and the Vendors tab (when purposes are shown)

Features

Legal basis dropdown

Code Changes

• Update typescript types in admin-ui
  • This really doesn't affect fides-js, but it's easier to generate then copy/paste from admin-ui. we've let the admin-ui types get stale
• Update fides-js types
• Add descriptions to features
• Fix bug where systems were not being rendered on purposes anymore (after they got separated from vendors)
• Add legal basis dropdown
• Update cypress tests

Steps to Confirm

• Add some data uses that have legal bases of either "Consent" or "Legitimate interest"
• Add data uses that have Features which exist in the GVL (for instance, Match and combine offline data sources)
  Example:
  

Note: make sure your "Features" save!! You need to hit "Enter" after typing it in, since it's actually a multiselect field

• Visit fides-js-demo.html and see your features and legal basis dropdowns render

Pre-Merge Checklist

• All CI Pipelines Succeeded
• Issue Requirements are Met
• Update CHANGELOG.md
