Auto merge of rust-lang#135292 - lqd:rustcperfup, r=kobzol

bump `rustc-perf` submodule

This updates the `rustc-perf` submodule to pull in the recent changes, in particular the error handling in rust-lang/rustc-perf#2021 fixing the error we saw in a recent run.

I think I did this correctly, submodules are so annoying.

r? kobzol

(opening as draft to do a perf run and check that nothing has changed indeed)
