cli_classic: Add convenient '--{flash,get}-size' cli opt

We have this in the ChromiumOS fork of flashrom which we rely
on to obtain the current flash chip in use. This ports it for
upstream consumption.

V.2: Constrain number_of_operations to one as per Nico's comment.
V.3: Rename '--get-size' to '--flash-size' however keep old arg as
     'undocumented' for back-compat.
V.4: Add missing --help line.
V.5: Add man page entry.
V.6: Use printf() directly.
