Include the untarred segment size when uploading segment in METADATA mode

Currently there is no way to know the untarred segment size when uploading segment in METADATA mode because controller doesn't download the segment for performance concern. With #11193 we use tarred segment size as an approximate untarred segment size for storage quota check, but we should include the size when uploading the segment.
We can consider always including the untarred segment size for all upload mode because this information should be available on the segment generator side.
