[Telemetry] Update Adjust campaign id telemetry

[liuche]

This is a follow-up to #7295.

In order to actually track retention by campaign, we need the following:

Acceptance Criteria

• Add client_id to the installation ping (this doesn't include GAID, and was broken out as a custom ping from metrics ping because the campaign id wasn't always available on startup)
• Update Adjust id in metrics ping to match the Adjust fields included in the installation ping, because using just the ad id is out of date.
  • I can see these values in the installation and metrics ping in Glean

@magorlick confirmed she can see these fields now, so closing this as done.
