When context disposal rate is high and we cannot perform a full GC, we do nothing until the context disposal rate becomes lower.

Add mode to reduce memory usage in idle notification.
...
While the mutator is active, the idle time handler optimizes for latency by doing only incremental steps and scavenges.
When the mutator becomes inactive, the idle time handler forces few incremental GCs to reclaim memory and then stops until mutator is active again.

Ensure that GC idle notifications either make progress or stop requesting more GCs.
...
The V8::IdleNotification will only return 'True' when the gc idle time handler
thinks there is no more GC which can be done. However, the gc idle task handler
can end up repeatedly making no progress (e.g., if it can't finalize a sweep)
which causes idle tasks to be repeatedly scheduled in Chrome which do nothing
but wake up Chrome. Fix this by returning Done if we can't make any progress
within an Idle Round.

Simplified garbage collection idle handler.
...
The current GC idle time handling heuristics are getting too complicated. Moreover, with longer idle time we are getting more full garbage collections. This CL shrinks the idle round window and reduces complexity in the case where we cause a full garbage collection.
