Subject: [PATCH] ci: the portable macOS and Windows jobs run as their own
 workflow

GitHub serves a job's log only when its whole run has completed, and
the Linux `check` takes over an hour, so a macOS failure's reason was
unreadable for that long while the portable jobs sat in the same run.
Each OS's run now completes on its own; the jobs are unchanged.
