[CT-1367] New tracking event: Adapter info

[iknox-fa]

We currently try to get the adapter information for tracking purposes long before we actually load the adapters-- this causes a bunch of issues where we have to parse projects and such just to track the invocation. Since there's no benefit to this in terms of our analytics, this approach has been changed in this PR.

This ticket encompasses the work necessary to properly report adapter info at such a point that we actually load the adapters. This includes the work to update the internal analytics project to reflect the change in raw event data.

Specifically we need adapter_type and adapter_unique_id as indicated here.

This includes the work to update the internal analytics project to reflect the change in raw event data.

For simplicity, let's kick this out of scope for here, and open a new issue in our internal-analytics repo instead to track this as follow-up work: https://github.com/dbt-labs/internal-analytics/issues/1402
