testing: improve area below filter

With results, the area is both more compact and useful. Passed/Total
tests are shown on the left, with an icon summarizing the view. On the
right, the wall-clock duration of the tests and a button to rerun tests.
The alt action on the button reruns the tests with the debugger.
Previously the rerun action was not very discoverable--had a few issues
about it over the course of time.

There's also no awkward gap when there's no test results:

Fixes #188841
