LP-304 - Allow further info to be added to PERF_INIT_COUNTER for future feature support.
This may allow in future to extract the counters id list with grep to be handled by gcs or other custom tools
Proposed usage:
PERF_INIT_COUNTER(counterVariable, id, "MODULE NAME","COUNTER DESCRIPTION","UNIT OF MEASURE");
i.e.:
PERF_INIT_COUNTER(counterExecutionTime, 0xAC700001, "ACTUATOR", "Actuator update execution time", "uS");
