Add `winapi` (or variant thereof) as benchmark to perf.rust-lang.org

[pnkfelix]

Spawned off of #48247

There have been instances where we have injected performance issues when compiling winapi

It has been suggested that we add winapi as a standard benchmark.

(In general I would like to revisit our benchmarks as a whole, which I guess is a task covered by #48750.)

This issue is more targeted: We should add winapi, or a variant that captures its workload but works on Linux hosts, to the set of rustc benchmarks that live on perf.rust-lang.org.

A similar issue exists here: rust-lang/rustc-perf#181

Seems reasonable to track this just on rustc-perf for now, so going to close this in favor of that.
