Summary:
ES Modules implicitly enable strict mode. Adding the "use strict" directive is, therefore, not required.
This diff removes all "use strict" directives from ES modules.

Reverting the import to the previous local module style since importing from react-native seems to introduce some perf regression. We'll revisit this later in the future.

Summary:
`setTimeout` inside a headless JS task does not always works; the function does not get invoked until the user starts an `Activity`.
This was attempted to be used in the context of widgets. When the widget update or user interaction causes the process and React context to be created, the headless JS task may run before other app-specific JS initialisation logic has completed. If it's not possible to change the behaviour of the pre-requisites to be synchronous, then the headless JS task blocks such asynchronous JS work that it may depend on. A primitive solution is the use of `setTimeout` in order to wait for the pre-conditions to be met before continuing with the rest of the headless JS task. But as the function passed to `setTimeout` is not always called, the task will not run to completion.
This PR solves this scenario by allowing the task to be retried again with a delay. If the task returns a promise that resolves to a `{'timeout': number}` object, `AppRegistry.js` will not notify that the task has finished as per master, instead it will tell `HeadlessJsContext` to `startTask` again (cleaning up any posted `Runnable`s beforehand) via a `Handler` within the `HeadlessJsContext`.
Documentation also updated here: https://github.com/facebook/react-native-website/pull/771
### AppRegistry.js
If the task provider does not return any data, or if the data it returns does not contain `timeout` as a number, then it behaves as `master`; notifies that the task has finished. If the response does contain `{timeout: number}`, then it will attempt to queue a retry. If that fails, then it will behaves as if the task provider returned no response i.e. behaves as `master` again. If the retry was successfully queued, then there is nothing to do as we do not want the `Service` to stop itself.
### HeadlessJsTaskSupportModule.java
Similar to notify start/finished, we simply check if the context is running, and if so, pass the request onto `HeadlessJsTaskContext`. The only difference here is that we return a `Promise`, so that `AppRegistry`, as above, knows whether the enqueuing failed and thus needs to perform the usual task clean-up.
### HeadlessJsTaskContext.java
Before retrying, we need to clean-up any timeout `Runnable`'s posted for the first attempt. Then we need to copy the task config so that if this retry (second attempt) also fails, then on the third attempt (second retry) we do not run into a consumed exception. This is also why in `startTask` we copy the config before putting it in the `Map`, so that the initial attempt does leave the config's in the map as consumed. Then we post a `Runnable` to call `startTask` on the main thread's `Handler`. We use the same `taskId` because the `Service` is keeping track of active task IDs in order to calculate whether it needs to `stopSelf`. This negates the need to inform the `Service` of a new task id and us having to remove the old one.
