Add cloning Persistent Storage to the progress bar progress.
This MR is based on !1302 (merged)
Closes #20042 (closed) and #19887 (closed) and #11932 (closed)
The current design is a cumulative progress bar for TAILS partition and TailsData partition.
I used psutil.disk_usage().used
to get the Clone Persistent Storage progress and totalsize.
