Subject: Add 'MemUsageBytes' format option

Although storage is more human-readable when expressed in SI units,
IEC/JEDEC (Bytes) units are more pertinent for memory-related values
(and match the format of the --memory* command-line options).

(To prevent possible compatibility issues, the default SI display is
left unchanged)

See https://github.com/containers/podman/issues/8945
