Pablo Erhard c5635b82c9 perf_hooks: sample delay per event loop iteration

Add a samplePerIteration option to monitorEventLoopDelay that records
event loop delay from libuv event loop iterations instead of the timer
interval sampler. The default remains interval-based; existing uses of
monitorEventLoopDelay() keep behaving the same unless the
samplePerIteration option is passed through.
