perf_hooks: introduce createHistogram
Adds a new `perf_hooks.createHistogram()` API for creating histogram
instances that allow user recording.
Makes Histogram instances cloneable via MessagePort. This allows, for
instance, an event loop delay monitor to be running on the main thread
while the histogram data can be monitored actively from a worker thread.
