TC-IDM-12.1: Add a wildcard dump test (#33878)

* TC-IDM-12.1: Add a wildcard dump test

This is a convenience test for the test harness that creates a
device dump for submission as a part of the certification materials.
Putting this as a separate test means we don't need to ask the
testers to mess around with setting parameters for this test in
the test harness.

* linter

* add wildcard read as a step

* slight re-wording
