Segfault caused by logger on Windows

[johnwason]

Logging was causing segfaults in numerical_ik_unit.cpp and simple_collision_unit.cpp unit tests on Windows. The logging has been disabled by commenting out gLogLevel = util::LevelDebug; in the test fixtures. See
https://github.com/tesseract-robotics/trajopt/actions/runs/5300211470/jobs/9593645305 for example output. This segfault problem only occurs on GitHub actions. The tests run normally locally.
