Check all crates (paritytech#12709)

* check all crates individually

It's relevant to check workspace crates individually because otherwise their compilation problems
due to feature misconfigurations won't be caught, as exemplified by
paritytech#12705

* adapt to lack of multiple macos runners

paritytech#12709 (comment)

* fix cancel-pipeline-cargo-check-each-crate-macos

* fix cargo-check-each-crate-macos again

* time command execution

* fix YAML anchors

* add explanation for rounding division

* ensure the minimum of one crate per group

* collect artifacts for pipeline stopper

* revert hardcoded crates_per_group

* re-add crates_per_group=1
