MR Widget Extension Telemetry - `WidgetTerraform`

What does this MR do and why?

For #366652 (closed)

This adds metrics around existing tracking events for the Terraform widget extension.

Unfortunately, defining the metrics for each of these widgets requires around 500 Lines of Code and 21 files modified, so I am splitting them up into their own MRs.

This is all piping for tracking data.

How to set up and validate locally

This is just adding Metrics, so there really isn't anything to test locally.
