Bug 1964705 - Retrigger select perf tests on autoland. r=perftest-reviewers,taskgraph-reviewers,jmaher,kshampur

Our goal here is to increase the speed of detecting performance changes
Our current detection methods required 12 data points to make a decision on if a regression has happened.
Rather than backfilling, and causing builds to run(and overload their capacity) we are choosing to retrigger the same datapoints
