perf mem: Clean up output format

Now, "--phys-data" is the only option which impacts the output format.

A simple "if else" is enough to handle the option. But there will be
more options added, e.g. "--data-page-size", which also impact the
output format. The code will become too complex to be maintained.

Divide the big printf into several small pieces. Output the specific
piece only if the related option is applied.

No functional change.
