perf_hooks: multiple fixes for Histogram

* The createHistogram(options) options weren't actually implemented
* Add a new count property that tracks the number of samples
* Adds BigInt options for relevant properties
* Adds add(other) method for RecordableHistogram
* Cleans up and expands tests
* Eliminates unnecessary ELDHistogram native class
* Improve/Simplify histogram transfer impl
