Gather Jan 2026 capacity and usage metrics

[smlambert]

This issue will be used to gather relevant data to determine where we have long queue times, what our current average execution times are for AQAvit tests and where we would get most positive impact if we added or changed our infra capacity (static or dynamic) during release periods.

[smlambert]

Average test job queue and execution times

Where queue time is part of the total execution time (execution time includes queue, setup, build, test, post stages) and execution time also includes auto-rerun child jobs. 9 top-level targets comprise the set that is required to pass in order to become AQAvit verified, so we will focus on those jobs first and consider other top-level targets at a later time.
