New TCF Purpose Header Field on Translations (#5246)

- Adds a new purpose_header field on the ExperienceTranslation and on the historical record, the PrivacyExperienceConfigHistory table
- Adds a data migration to populate purpose_header fields on all existing TCF translations as well as update the existing description, provided the customer is still on version 1 for that translation, meaning they've made no edits
