* 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.

When a request with a long payload is received, http2 does
not allow a response that does not process all the incoming
payload. Add a conditional Http2Stream.close call that runs
only if the user hasn't attempted to read the stream.

Remove the `performance.getEntries()` and `performance.clear*()`
variants and eliminate the accumulation of the global timeline
entries. The design of this particular bit of the API is a memory
leak and performance footgun. The `PerformanceObserver` API is
a better approach to consuming the data in a more transient way.

Add missing clear() method to `perf_hooks.performance` to
remove the entries from the master timeline to prevent
that from being a memory leak.
