Add Share module

Summary:
revision of https://github.com/facebook/react-native/pull/5476

It has only one method `shareTextContent` and next will be`shareBinaryContent`.

In Android, Promise can't receive a result, because `startActivityForResult` is not working with `Intent.ACTION_SEND`. Maybe we can use `createChooser(Intent target, CharSequence title, IntentSender sender)` which requires API level 22.
Closes https://github.com/facebook/react-native/pull/5904
