perf_hooks: complete overhaul of the implementation
* Update the user timing implementation to conform to
  User Timing Level 3.
* Reimplement user timing and timerify with pure JavaScript
  implementations
* Simplify the C++ implementation for gc and http2 perf
* Runtime deprecate additional perf entry properties
  in favor of the standard detail argument
* Disable the `buffered` option on PerformanceObserver,
  all entries are queued and dispatched on setImmediate.
  Only entries with active observers are buffered.
* This does remove the user timing and timerify
  trace events. Because the trace_events are still
  considered experimental, those can be removed without
  a deprecation cycle. They are removed to improve
  performance and reduce complexity.
