…est builders

Also annotate calls to tooSlow with specific reasons.

This will somewhat reduce test coverage on the 'darwin' builders until
we have darwin 'longtest' builders (#35678,#49055), but still seems
worthwhile to avoid alert fatigue from tests that really shouldn't be
running in the short configurations.

Updates #58918.
Updates #58919.
Fixes #58937.
