Media: Update file size meta data when editing images.

Fixes an error in which the file size meta data retained the original upload's values follow a user editing the images in the media screen.

The original images' file sizes are now stored in the backup image data to allow for them to be restored when a user restores the original image.


Props ankit-k-gupta, antpb, audrasjb, chaion07, gauravsingh7, joedolson, oglekler, pls78, rajinsharwar, sayedulsayem, vertisoft.
Fixes #59684.
