Modify the RenderThread to track the number of widgets
and "hidden widgets" which are running through that thread.
By knowing the if the widgets are all hidden, the thread
can accurately inform V8 when it is idle so that V8 can
better cleanup unused memory when idle.
This time - if V8 has been killed for some reason, don't
call into it.
