[FR] Add API to provide custom profilers #1807 (#1809)
This API is akin to the MemoryManager API and lets tools provide
their own profiler which is wrapped in the same way MemoryManager is
wrapped. Namely, the profiler provides Start/Stop methods that are called
at the start/end of running the benchmark in a separate pass.
