utility: Added Tracer for collecting time measurements

* define TRACING_ENABLED in utility/tracing.h to enable tracing
* invoke TraceEvent by writing TRACE() at start of function or scope
* provide an event name with TRACE("name")
* press SPACE to show collected traces history and report with accumulated times
