Multisite networks have a variety of use cases, and in many of them single-site administrators are not trusted to take actions that affect the whole network, require making decisions about legal compliance, etc. By default, those actions should require super admin capabilities. Plugins can be used to override that behavior if a particular site's use case calls for it.

This runs immediately after the data export file has been successfully created, allowing plugins to introduce some workflow customizations. For example, a plugin could password-protect the export file, for peace of mind, even though the CSPRN in the filename makes brute force attacks nearly impossible.

The primary means of protecting the files is the CSPRN appended to the filename, but there is no reason to keep the files after the data subject has downloaded them, so deleting them provides an additional layer of protection. Previously this was done from `wp_privacy_generate_personal_data_export_file()`, but that does not guarantee that it will be run regularly, and on smaller sites that could result in export files being exposed for much longer than necessary.
`wp_privacy_delete_old_export_files()` was moved to a front end file, so that it can be called from `cron.php`.
This introduces the `wp_privacy_export_expiration` filter, which allows plugins to customize how long the exports are kept before being deleted.
`index.html` was added to the `$exclusions` parameter of `list_files()` to make sure that it isn't deleted. If it were, then poorly-configured servers would allow the directory to be traversed, exposing all of the exported files.

`rand()` is deterministic and therefore offers much less protection in this context. `wp_generate_password()` is a convenient wrapper around `wp_rand()`, which uses `random_int()` to generate cryptographically-secure psuedorandom numbers.

While caching here seemed like a good idea in theory, in practice the cache would be often stale causing development issues.
We exclude common folders (such as `node_modules`) from the scanning to avoid directories which are not useful to the end-user, so as long as those exclusion lists are held up this shouldn't cause too much of a degredation in the future.
We may consider adding caching here again in the future if it's determined that it is really needed.

This sets a referrer policy of `same-origin` which adds hardening by preventing a referrer being sent from the admin area or login screens to other origins. This helps prevent unwanted exposure of potentially sensitive information that may be contained within URLs.
This change introduces a new filter, `admin_referrer_policy`, for filtering the referrer policy header value. The header can be disabled if necessary by removing the `wp_admin_headers` action from the `admin_init` and `login_init` hooks.

* After writing a change to a PHP file for an active theme or plugin, perform loopback requests on the file editor admin screens and the homepage to check for fatal errors. If a fatal error is encountered, roll back the edited file and display the error to the user to fix and try again.
* Introduce a secure way to scrape PHP fatal errors from a site via `wp_start_scraping_edited_file_errors()` and `wp_finalize_scraping_edited_file_errors()`.
