Rollup merge of rust-lang#112787 - oli-obk:gha_tinder_for_problems, r=jyn514

Add gha problem matcher

These regexes capture rustfmt errors, panics and regular Rust errors in CI and automatically add messages in the diff view. This should make it simpler to quickly see what went wrong without having to scroll through CI logs.

We can fine tune the regexes or add more matchers after having a look at how it actually works in practice
