Rollup merge of rust-lang#74600 - Mark-Simulacrum:try-perf, r=pietroalbini

Enable perf try builder

This adds a dedicated branch for perf to use for CI, intended to allow perf to
enqueue builds without needing to use bors. bors is great, but bors requires an
open PR to work, and we want to invoke perf on closed PRs sometimes (in
particular, rollups).
