This CL moves the call to GCTracer::StopCycle for the full GC from
Heap::CompleteSweeping full, which is called to force sweeping to
finish, to GCTracer::NotifySweepingComplete, which is called as soon
as sweeping finishes --- and symmetrically to a new method
GCTracer::NotifyCppGCCompleted, which is called as soon as sweeping
of the managed C++ heap finishes. In this way, a full GC cycle is
reported as soon as sweeping is finished both for the V8 and the C++
managed heap.
The changes introduced in this CL are essentially a partial revert of
https://crrev.com/c/3456563, fixed in such a way that when the full
GC cycle is reported, the current tracer event will be the correct
one corresponding to that cycle.
