Joyee Cheung 4ee4718857 src: save the performance milestone time origin in the AliasedArray
Previously we cache the time origin for the milestones in the user
land, and refresh it at pre-execution. As result the time origin
gets serialized into the snapshot and is therefore not deterministic.
Now we store it in the milestone array as an internal value and
reset the milestones at serialization time instead of
deserialization time. This improves the determinism of the snapshot.

Drive-by: remove the unused MarkMilestone() binding.

The HTML structured serialize algorithm treats transferable and

1. Enforce receiver checks on IDL interfaces.
2. Avoid prototype manipulation on constructing IDL interfaces with
   `ReflectConstruct`.
3. `defineReplaceableAttribute` should create IDL getter/setter.
4. Corrected `PerformanceResourceTiming` to inherit the public interface
   `PerformanceEntry` instead of the internal interface
   `InternalPerformanceResourceTiming`.
5. `detail` is not a specified attribute on `PerfomanceEntry`. Node.js
   specific extensions are moved to a subclass of `PerformanceEntry` as
   `PerformanceNodeEntry`.

Add WebPerf API `performance.setResourceTimingBufferSize` and event
`'resourcetimingbufferfull'` support.

The resource timing entries are added to the global performance
timeline buffer automatically when using fetch. If users are not
proactively cleaning these events, it can grow without limit. Apply
the https://www.w3.org/TR/timing-entrytypes-registry/ default
resource timing buffer max size so that the buffer can be limited
to not grow indefinitely.

legendecas 062f8e3730 perf_hooks: web performance timeline compliance
All API introduced in this PR are compliant with web
[performance-timeline](https://w3c.github.io/performance-timeline)
spec. "performance-timeline" is listed as supported web spec in the doc
https://nodejs.org/docs/latest/api/perf_hooks.html#perf_hooks_performance_measurement_apis.

Changes summary:
1. Add new supported wpt test subsets: user-timing and
  performance-timeline.
2. Add support for `Performance.getEntries`,
  `Performance.getEntriesByName` and `Performance.getEntriesByType`
  to synchronously fetch buffered performance entries. This means
  the user should invoke `Performance.clearMarks` and
  `Performance.clearMeasures` to clear buffered entries to prevent from
  those entries been kept alive forever.
3. Add support (again after https://github.com/nodejs/node/pull/37136)
  for `buffered` flags for `PerformanceObserver`.
3. Fixes `PerformanceMark` and `PerformanceMeasure` wpt compliance
  issues.
4. Only user-created performance entries will be buffered globally. This
  behavior should be compliant with
  https://w3c.github.io/timing-entrytypes-registry/#registry.

With the new ability to fetch user-created performance entries
synchronously, the issues raised in
https://github.com/nodejs/diagnostics/issues/464#issuecomment-861920116
could also be fixed.

* 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.
