Add new benchmark metrics to testlib
QElapsedTimer provides nanosecond-resolution elapsed timing, which
allows for finer granularity benchmark reporting. Also, clients
may also wish to benchmark the memory usage of a particular component,
but no metric currently exists which matches that requirement.
This commit adds the WalltimeNanoseconds and BytesAllocated metrics
to meet these needs. It is intended for manual use by clients via
setBenchmarkResult() only.
