Improve the roctx markers performance when the tracer is not engaged
(the application is not running with rocprof).
The performance of roctx push/pop, measured with:
-----------------------------------------------------------------------
auto start = std::chrono::steady_clock::now();
for (int i = 0; i < 10000000; ++i) {
roctxRangePush ("A");
roctxRangePop ();
}
auto end = std::chrono::steady_clock::now();
std::cout << "ns = " << std::chrono::nanoseconds(end - start).count()
/ 10000000 << std::endl;
-----------------------------------------------------------------------
