Add timer to file copy process (stage 1 setup)

Just as in the past usage boxes for (kernel) memory were added for stage 1 file copying, I'd like to request a timer to be added as well, and/or a debugprint to logs, during this file copy process.

Reason is the smoothness and speed of the file copying process can vary depending on how much memory ReactOS has available. Expected output would be something like:

graphical: "Done copying 350 files (140MB) in 1m:10s"

log: "Done copying 350 files (140MB) in 70s (2000KB/s) using 128MB RAM"

Expected result is this "2000KB/s" will be a lot lower on low memory situations (20 to 40MB).

Think I've seen file copying process take anywhere from between 1 minute (64MB+) and 15 minutes (around 40MB RAM or lower). A bad result if you're outmatched by a simple unbuffered DOS XCOPY /S
(and yes I know a .cab file is being extracted).
