Rename the "precheck" stage in CI to "quick-checks"

Most jobs in the "precheck" stage spend more time setting up their
environment than running the script (seconds), this allows us to add a
small always on dedicated runner instead of the autoscaled ones.

Hence, the stage is renamed to "quick-checks", and a tag "smalljob" is
added to the anchor so that these jobs are picked by the dedicated
runner.

(cherry picked from commit 9aa5041a88)
