tests: latency_measure: allow use of other timer for timestamp

Some platforms have slow system clock resulting in not very
accurate latency measurements. This updates how the timestamps
are obtained by copying the mechanism from the timing_info test.
This allows using alternate higher speed timers to measure
latency.
