Samuel Susla a8d0dd6646 Implement task continuation 
Summary:
Changelog: [internal]

Scheduler's callback have option to add more work inside callback. This work stays on top of the priority queue and gives React ability to flush all work synchronously if need.

This diff adds use of `shouldYield_` to the workLoop. For now, it always evaluates to false. In the future when we allow access to the scheduler to native, it will allow yielding.

Relevant code in JavaScript:

Samuel Susla 06753d431a Add expiration date to Task and use it to determine priority 
Summary:
Changelog: [internal]

To prevent starvation, this diff implements expiration time as a way to order tasks in priority queue. This stops higher priority tasks from preventing lower priority tasks from running. The same mechanism is implemented in [JavaScript's scheduler](https://github.com/facebook/react/blob/master/packages/scheduler/src/forks/SchedulerNoDOM.js).
