Re-enable the src/test/debuginfo/mutex.rs test on Windows

This test required a newer version of cdb than was previously enabled in
CI thus leading to some bitrot in the test since the time it was
originally created. With the update to the `windows-latest` image last
week, we're now running this test in CI and thus uncovered the
regression.

I've updated the test and it now passes.
