Implement NTP-SI confirmations

[tmancey]

Confirm NTP views and clicks so that users are rewarded for NTP sponsored images. See #3234 as we need to pass the creative_instance_id from the CRX changes.

This work is in branch brave-core.1.16.x-ntp-si-confirmations

[kylehickinson]

As discussed, currently implementation is incomplete, requires updates to JSON parsing

[tmancey]

@kylehickinson I have upgrade the JSON parsing to reflect the new photo.json format for NTP sponsored images, can you please review brave-core.1.16.x-ntp-si-confirmations.
