VmPerfEval: Adding a TSC -> real time conversion script

The ApicTimerTest records the delay times in TSC ticks. This
does make it difficult to compare across different CPUs (even
of the same make) that will have different TSC tick rates.

This patch will convert all the appropriate CSV files within the
test output directory into ones that have real time units. This
will make it easier to compare as the delays will be provided
in common units.

BUG=b:266974799
TEST=Ensured correct conversion on previously captured test results
