Switch lock_tracing to litebox_util_log

[jaybosamiya-ms]

This PR switches out lock_tracing functionality away from DebugLogProvider based implementation to the #665-based logging facade, in preparation for full remove of DebugLogProvider.

It also adds a reminder to turn on LITEBOX_LOG inside dev_bench, where previously stderr showed things, but now you need to remember to do LITEBOX_LOG.
