Adds a trace event to the platform tracing system. These function calls are usually the result of a TRACE_* macro from trace_event_common.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.

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().
