We only need included categories list, excluded categories list will only work
if we use regular expression in categories list, which is not supported in V8.

The state sampling was implemented in chrome, we had an interface for it
V8 but it was not implemented yet.
The chrome version version has been removed in
https://codereview.chromium.org/2406703002/
Therefore following up with its removal in V8 as well.
This CL can land independent of the Chromium related CL.

Escape sequences may now be written to a trace file (previously,
any string with a valid escapable character would fail a check).
Also, string properties are now surrounded with quotes.

V8 has had a trace event macro interface for while, but without a tracing
controller a standalone V8 would be unable to collect traces.
This CL introduces a complete Tracing Controller system for V8.
It is fully function except that it does not yet store trace event args.

The tracing controller itself, contributed by the author of this CL
