Files.app: Call FreeDiskSpace before starting copy.
Previously Files.app can run out of local storage by copying files to Downloads.
The CL let fileManagerPrivate API call FreeDiskSpace before starting copy so
that it can secure available space by removing drive caches.
If it cannot secure available space, the API returns QuotaExceededError.
