Original issue's description:
> [Tracing] Embed V8 runtime call stats into tracing.
>
> Currently we have V8 RuntimeCallStats that is independently from tracing when
> running d8 with flag --runtime_call_stats. This patch embeds V8 runtime call
> stats into tracing, by having a global table of runtime call counters each
> isolate, resetting the table each time we enter a top level trace event, and
> dumping the table for each top level trace event. This will make trace file more
> compat, as well as enable runtime call stats in tracing system.
>
> This patch adds ~5% overhead to V8 when the category is enabled, we measure the
> overhead by running a script when category is enabled.
