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.

- Move Performance and InternalPerformance to a new
lib/internal/perf/performance.js
- Move now() getMilestoneTimestamp() into
lib/internal/perf/utils.js
- Rename lib/internal/perf/perf.js to
lib/internal/perf/performance_entry.js
- Refresh time origin at startup (this means the
time origins could differ between snapshot building
time and snapshot creation time)

* 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.
