Update Version Hash Contents

[pattisdr]

Closes https://github.com/ethyca/fidesplus/issues/1172

Description Of Changes

Update the contents of the version hash that is used to determine when consent should be resurfaced for TCF. Previously we hashed purpose x legal basis and vendor x legal basis to match what could be saved in the string. This largely updates to save three dimensions together vendor x legal basis x purpose and also includes AC vendors and other applicable systems in the hash, as well as determination of whether vendors moved from GVL 2 to GVL 3

New sections are:
  - Policy version (no change)
  - Vendor purpose consents
  - Vendor purpose legitimate interests
  - gvl vendors disclosed

Code Changes

• Updates the fields in TCFVersionHash which is the object built prior to constructing the version hash

Steps to Confirm

• Set tcf_enabled is True, run nox -s dev -- shell
• Add GVL System
• GET Privacy Experiences with include_meta query param:

curl -X 'GET' \
  'http://localhost:8080/api/v1/privacy-experience?show_disabled=true&region=eea&systems_applicable=false&include_gvl=false&include_meta=true&page=1&size=50' \
  -H 'accept: application/json'

• Note stays the same on repeated API calls.
• Add new system, or add new GVL purpose to an existing system or update the legal basis of an existing GVL purpose. Note the hash changes.
