Render new TCF fields in the overlay using the data map

[allisonking]

Closes #4255

Description Of Changes

Renders the following TCF fields from data from the data map as opposed to querying gvl.json directly:

• cookie storage disclosure copy
• retention periods for purposes in a vendor
• privacy policy/legitimate interest disclosure urls

Not all of these fields were fully passed over from the backend, so there are some backend changes in this PR as well.

Code Changes

• Update TS types
• Simplify some logic now that vendor relationships contain all vendors
• Derive storage disclosure info from TCFVendorRelationships
• Add privacy_policy_url to TCFVendorRelationships in the backend
• Derive urls from TCFVendorRelationships
• Add retention period to EmbeddedPurposes in vendor data
• Remove no longer needed GVL types
• Cypress tests

Steps to Confirm

• Set up TCF and on one of those systems, fill out the "Cookie properties" section in admin-ui for the system
• Spin up the TCF overlay and you should see these cookie properties reflected in the vendor tab, when you click on a vendor
  
• Edit the system's privacy policy and legitimate interest disclosure. This should reflect in the TCF overlay
  
• In one of the system's data uses, change its "Retention period" to a different number. You should see this reflect in the "Purposes" section in the vendor
  

Pre-Merge Checklist

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

@allisonking backend is looking good from my POV - nice work! i can see now it wasn't quite as straightforward as it seemed when talking it over. just had a small nit on the fixtures, though it's nuanced enough that i wouldn't blame you if you choose to ignore me 👍

and i'd like @pattisdr to also confirm things look good, since i'm still pretty fresh in the overlay generation codepath!

[pattisdr]

Reviewing now!

[pattisdr]

Noting concerns about differences in retention periods on the same Purpose across Systems or within the same System -

[allisonking]

Thanks for all the assistance @pattisdr and @adamsachs ! I think this is ready for review now 👍

[pattisdr]

Thanks Allison, starting review!

[pattisdr]

Nice work Allison, especially moving some of this from the GVL into being pulled from the datamap in the backend. Mostly minor cleanup and another test requested!

[pattisdr]

wonderful job 🌞

[allisonking]

thanks for the thorough review @pattisdr !
