Extends TargetRequests with content and (meta)data callback

[jeffreydelooff]

Exposes the native content with metadata callback to React Native. Currently it is not possible to retrieve the responseTokens or analytics payload as described for Android and for iOS.

Description

Added

• a new TargetRequestObjectWithData which registers a callback containing both the content, data and error.
• both native iOS and Android implementations to expose the contentWithDataCallback to RN

Related Issue

Exposes additional already existing native SDK functionality.

Motivation and Context

Currently it is not possible to retrieve any additional (meta)data from a TargetRequest.

How Has This Been Tested?

Added unit tests and tested this with assurance in an existing project. Tracked the Target requests and its metadata. Added an analytics edge event to track this data.
