Provide a hint for the idle notification handler.

Provide a hint for the idle notification handler.

The IdleNotification() function accepts an optional hint argument since V8 3.8.1 (rolled in r114984). 

This argument roughly specifies the expected duration of the idle pause and thus defines the amount of work to be done in the function. There is no guarantee that the actual work will match the hint though.

This CL provides hints for idle notifications sent from the foreground tab depending on the idle timer delay. This somewhat reduces idle notification pauses at the beginning of "idleness" period.

Could you please take a quick look?

This small adjustment slightly reduces idle notification pauses in the
foreground tab.

I'm not familiar with this code at all, so I'm a poor reviewer. if you just need
an owner to rubberstamp l g t m after a review, i can do that, but someone else
should review this.

John, I am redirecting the review to Erik, but we would need your rubberstamp
lgtm before landing.

Erik, could you please take another look? I addressed the issue we discussed
offline.

Is this change waiting for something?
