Auto merge of #114623 - Kobzol:opt-dist-gha-summaries, r=<try>

Print some information from try builds to GitHub summary

This PR adds some logs from `opt-dist` (the duration of the individual steps of the build pipeline, and the size of the resulting artifacts) to GitHub [job summaries](https://github.blog/2022-05-09-supercharging-github-actions-with-job-summaries/), in order to quickly show useful information right in the GHA CI job page, without needing to read the full log.

[This](https://github.com/rust-lang-ci/rust/actions/runs/5810621086) is how the summary currently looks like.
