Samuel Susla e9016f8b73 Handle $$typeof call in RuntimeSchedulerBinding
Summary:
Changelog: [internal]

Explicitly return undefined for `$$typeof` inside RuntimeSchedulerBinding.

React calls `$$typeof` on RuntimeScheduler. To make sure assert only triggers if unsupported value is requested, it needs to be explicitly handled

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).

Samuel Susla cc3e87c45b Implement RuntimeScheduler::getShouldYield
Summary:
Changelog: [internal]

Implement RuntimeScheduler::getShouldYield and expose it through JSI.
For now we are only returning `false`. The value is backed by atomic_bool and in the future we will be able to indicate that React should yield to native.
