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.
