James M Snell	f3eb224c83	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.
