Stephan BehnkeandGitHub 6827aad2cc Report test crash (#8221)
## What changed?

Added a CI step that writes a crash JUnit XML file if the testrunner
doesn't complete.

## Why?

(1) Make the "Summary" helpful again by quickly seeing what went wrong.
(2) Make CodeCov show these crashes.
(3) Make our internal test report show these crashes.

## How did you test it?
- [ ] built
- [ ] run locally and tested manually
- [ ] covered by existing tests
- [x] added new unit test(s)
- [ ] added new functional test(s)

Example run:
