Summary:
…while an event is dispatched
While it is guarded, a copy of the Set is created before listeners are added or removed. The event dispatch loop continues with the old Set of listeners.
This PR modifies `BackAndroid` to match the proposal at the end of #5781.

Summary:
public
Map and Set are a standard JavaScript features, but are only supported in a subset of JSC versions that we target (e.g. iOS 7's JSC doesn't support Set).
The consequence of this is that failing to require('Set') before using it won't error during testing on a modern OS, but will fail on older OS versions. This diff makes the Map and Set polyfills available globally to all RN apps to avoid that problem.

See the Known Issues guide on the website.
We will work with the community to reach platform parity with iOS.
