The GDPR requires all users to be able to export their data, or request an export of their data. This is fine for active users as we have a data export button on user profiles, but suspended users have no way of accessing the data export function, and the workaround for admins to export data for suspended users involves temporarily unsuspending them, then impersonating the user to export the data as them.
Since suspended users no longer have access to their account, we can safely assume that the export request will be coming via a medium outside of Discourse (eg, email). This change is built with this workflow in mind.
This change adds a new "User exports" section to the admin user page, allowing admins to start a new export, and to download the latest export file.

Reverts 793915fe6aa1024b6a08cb8b042b7fb1e0bbece8. We no longer need this since we're destroying each posts in commit 028121b95b982500e0c63b11d216a6162d47a7bb.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
