Rollup merge of #113034 - jyn514:ci-progress, r=oli-obk

Switch some more Steps to `builder.msg`

In particular, this hides compiletest suites under a dropdown - some builders are configured with `verbose-tests`, which makes the suites take up many thousands of lines.

before:
```
Documenting stage1 cargo (x86_64-unknown-linux-gnu)
Check compiletest suite=rustdoc-js mode=js-doc-test (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu)
```

after:
```
::group::Documenting stage1 cargo (x86_64-unknown-linux-gnu)
::group::Testing stage1 compiletest suite=rustdoc-js mode=js-doc-test (x86_64-unknown-linux-gnu)
```
