Reimplemented from v8::TracingController.

Adds a trace event to the platform tracing system. These function calls are usually the result of a TRACE_* macro from trace-event-no-perfetto.h when tracing and the category of the particular trace are enabled. It is not advisable to call these functions on their own; they are really only meant to be used by the trace macros. The returned handle can be used by UpdateTraceEventDuration to update the duration of COMPLETE events.

Adds tracing state change observer. Does nothing in Perfetto SDK build (v8_use_perfetto = true).

Called by TRACE_EVENT* macros, don't call this directly. The name parameter is a category group for example: TRACE_EVENT0("v8,parse", "V8.Parse") The pointer returned points to a value with zero or more of the bits defined in CategoryGroupEnabledFlags.

Sets the duration field of a COMPLETE trace event. It must be called with the handle returned from AddTraceEvent().
