[devtools] qunit: update to 1.18.0 (closes #5533333)
* the logging API has changed (register callbacks instead of setting
attributes on the QUnit object)
* the logging callbacks all have a single "details" object argument
* the "main" div was renamed to "qunit-fixture" (this change is
responsible for all the churn in our own JS test files)
* QUnit can now build the DOM elements it needs for reporting from a
single "qunit" div

Documentation
~~~~~~~~~~~~~
Please keep rules semantically linked grouped together, with a comment about
what they are for.
Recommendation
~~~~~~~~~~~~~~
- Try to use existing classes rather than introduce new ones
- Keep things as simple as possible while in the framework
- Think about later customization by application
- Avoid introducing a new CSS file for a few lines of CSS, at least while the
framework doesn't include packing functionalities
