And move it to a different table so that we don't have to pay the
storage cost when not using it (most of the times).

Allow to quickly query all the files from a specific mimetype like in
the ResetRenderedTexts command.

When changing preview parameters (size, format, …), one can simply delete the preview folder and run
files:scan-app-data in order to retrigger updated preview recreation because files are absent.
However, that's not possible when using ObjectStorage as primary storage, as there's no concept of
"preview folder".
This command allows to simply delete and recreate the preview folder properly from
Nextcloud, so that the abstraction levels handle all the subfolder & file deleting part.

The command is meant to be used when the fonts used to render texts
("core/fonts/NotoSans-Regular.ttf" and "core/fonts/NotoSans-Bold.ttf")
are changed (for example, to add support for other scripts). The avatar
and text file previews will be removed, so they will be generated again
with the updated font when needed.

* `php occ preview:repair` - a preview migration tool that moves existing previews into the new location introduced with #19214
* moves `appdata_INSTANCEID/previews/FILEID` to `appdata_INSTANCEID/previews/0/5/8/4/c/e/5/FILEID`
* migration tool can be stopped during migration via `CTRL+C` - it then finishes the current folder (with the previews of one file) and stops gracefully
* if a PHP memory limit is set in the `php.ini` then it will stop automatically once it has less than 25 MiB memory left (this is to avoid hard crashes in the middle of a migration)
* the tool can be used during operation - possible drawbacks:
* there is the chance of a race condition that a new preview is generated in the moment the folder is already migrated away - so the old folder with the newly cached preview is deleted and one cached preview needs to be re-generated
* there is the chance of a race condition during access of a preview while it is migrated to the other folder - then no preview can be shown and results in a 404 (as of now this is an accepted risk)
