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.

Samuel Susla 318e9f283e Execute multiple tasks within single dispatch
Summary:
Changelog: [internal]

This brings native scheduler close to React's scheduler. React's scheduler executes all tasks in the queue within a single dispatch (they use setTimeout(0) for dispatch) and makes sure to not schedule two dispatches.
