Summary:
This is a follow up of the work by brentvatne in #5052. This addresses the feedback by astreet.
- Uses ReactChoreographer with a new callback type
- Callback dispatch logic moved to JS
- Only calls into JS when needed, when there are pending callbacks, it even removes the Choreographer listener when no JS context listen for idle events.
** Test plan **
Tested by running a background task that burns all remaining idle time (see new UIExplorer example) and made sure that UI and JS fps stayed near 60 on a real device (Nexus 6) with dev mode disabled. Also tried adding a JS driven animation and it stayed smooth.
Tested that native only calls into JS when there are pending idle callbacks.
Also tested that timers are executed before idle callback.
```
requestIdleCallback(() => console.log(1));
setTimeout(() => console.log(2), 100);
burnCPU(1000);
// 2
// 1
```
I did *not* test with webworkers but it should work as I'm using executor tokens.

Summary:
So `PanReponder.onPanResponderRelease/onPanResponderTerminate` receive a `gestureState` object containing a `onPanResponderTerminate.vx/vy` property. On Android and iOS, they appear to be orders of magnitude different, which appear to be due to the different scale of timestamps that are used when generating touch events.
This pull request fixes the timestamps to be milliseconds on both platforms (since I assume iOS is the more authoritative one, and is the one that `react-native-viewpager`'s vx thresholds written written to compare against.)
As far as I can tell, the RN code doesn't use the `vx/vy` properties, so they should be okay. And looks like the RN code only cares about relative values of `startTimestamp/currentTimestamp/previousTimestamp` though, so should be fine too. it's quite possible there will be downstream android breakage with this change, particularly for those who are already compensating for the RN discrepancy.

Summary: Calling setTimeout(f, 0) will currently schedule f to be called the next frame instead of immediately (which is how it behaves on iOS). This immediately calls back to JS and invokes the function.

Summary: Example of a conversion to web worker support using the ExecutionContext API changes made in the last set of web worker diffs. WebWorkerSample now creates timers to show that we can dispatch timer calls to multiple JS contexts.

Summary:
As a part of this change I'm also renaming SimpleArray to JavaOnlyArray and SimpleMap to JavaOnlyMap. The main reason for the change is to support use-cases such as driving animations form the native code. In the case of native "animated" I'd like to be able to use the same interface as JS is using for updating the View properties. As view setters can take ReadableMap and ReadableArray as an argument in some cases it is necessary to create and pass those types to the setter. Using WritableNativeArray and WritableNativeMap for this purpose seems to me like a misuse and IMO will be less performant (vs java-only map/array) as those implementations of ReadableMap and ReadableArray proxies all their methods through JNI.
I'm also adding some additional class-level comments for the moved classes to avoid confusion and hopefuly prevent people from using those classess accidentally while writing native modules or methods that calls to JS.
