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.
