Michael Lippautz 6bb35b8c83 handles: Only reclaim TracedNode during atomic pause 
TracedNode is used as backing node for v8::TracedGlobal (with
destructor) and v8::TracedReference (no destructor).

A future change adds concurrent marking for TracedReference which
requires that the node stays around until the atomic pause to avoid
synchronization with the concurrent marker.

This change prepares TracedNode in prolonging the lifetime until the
it is actively cleared ("sweeped") in the atomic pause. This allows
for spuriously keeping alive a TracedNode for an additional GC cycle
in the case the the node was destroyed while the marker is running.

We maintain eager clearing of nodes where possible, i.e., outside of
incremental marking.
