Description:

Adds the ability to use remote config to control AdAttributionPixelReporter and whether the token is added as parameter.

Steps to test this PR:
⚠️ Device is required to fully test this change. Attribution is not available on simulator.

2. Verify attribution pixel is fired including token parameter.
3. Remove the app, change includeToken setting to false in the linked configuration json file or remove setting object completely, verify attribution pixel is fired without token parameter.
4. Turn off the feature in configuration json, verify no attribution pixel is fired.
