tests: optionally write results as JUnit-style .xml
This will come in handy when publishing the results of Git's test suite during an automated Azure DevOps run. Note: we need to make extra sure that invalid UTF-8 encoding is turned into valid UTF-8 (using the Replacement Character, \uFFFD) because t9902's trace contains such invalid byte sequences, and the task in the Azure Pipeline that uploads the test results would refuse to do anything if it was asked to parse an .xml file with invalid UTF-8 in it.
