Samuel Susla 5e933fdd2a Yield for each access to the runtime
Summary:
changelog: [internal]

With multiple requests to the runtime, we need to make sure they are all granted before React continues with rendering. A boolean is not enough to track this. The first lambda that has VM will set it to false and subsequent requests will have to wait for React to finish rendering.

To prevent this, we can count how many lambdas are pending access to the runtime.

Summary:
D33740360 (https://github.com/facebook/react-native/commit/16ed62a850dd81bd9cc7f77ab3e77f42ed64b177) broke Explore VR on React Native. The app would go into a loop on boot and not finish mounting. This is probably a product code issue, but it's not a trivial issue to solve. Unlanding to unblock the RN migration.

Samuel Susla 6351064b75 Introduce RuntimeScheduler::callImmediates
Summary:
changelog: [internal]

React on web uses microtasks to schedule a synchronous update for discrete event. Microtasks are not yet available in React Native and as a fallback, React uses native scheduler and task with immediate priority. Until Microtasks are in place, React Native needs to make sure all immediate tasks are executed after it dispatches each event.

I tried to stay as close to [microtask standard](https://developer.mozilla.org/en-US/docs/Web/API/queueMicrotask) as I reasonably could.

Once microtasks on RN are shipped, this code can be removed.

Why note shared_ptr? Using shared_ptr suggests we are transferring ownership of object, which we are not.

Samuel Susla 74608417df Before removing a task from queue, make sure it was executed
Summary:
Changelog: [internal]

If task that is being executed schedules a new task with higher priority, the new task will be dropped from the queue. To fix this, we always check if the top of the queue is what was executed and only then remove it.

Example:
Let's say there is task A with priority "normal".

When we execute task A (which is not removed from the queue until later), it adds a task B with "immediate" priority.
So priority queue now has two tasks: [1: B, 2: A]

After task A finishes, inside workLoop, it will pop from top of the priority queue. But task A is no longer top of the priority queue (this is the bug) and it pops B. B is never executed and A is executed twice.

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.
