Add runtime-nativeaot-outerloop to build analysis (#113520)

We don't collect stats on these pipelines so the hit count on issues like #29383 don't get updated with hits in nativeaot runs.

At this point `runtime-nativeaot-outerloop` is more reliable than e.g. `runtime-libraries-coreclr outerloop` that hasn't seen a successful run in years.
