Use IBootstrap for the files_trashbin app

Only save login credentials in database once there is an external storage that needs it

only boot apps once

Add occ preview:migrate to migrate previews from the old flat structure to a subfolder structure

File entity to implement IIcon

in some cases `loadApp` is called more then once which is currently causing apps to be "booted" multiple times which can lead to unexepected behaviour with things like registering hooks

Mount the old previews in a separate folder for the multi bucket setup and check in them before using the actual locations

* introduces a new IRootMountProvider to register mount points inside the root storage
* adds a AppdataPreviewObjectStoreStorage to handle the split between preview folders and bucket number

* `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)
