Finish migration to litebox_util_log + remove DebugLogProvider

[jaybosamiya-ms]

This PR removes DebugLogProvider entirely by switching all the direct and indirect uses of it for logging to the litebox_util_log crate introduced in #665.

[jaybosamiya-ms]

Most of this is quite straightforward, but the repeated :% = format_args!(...) pattern makes me think I should update litebox_util_log to support :x or similar to easily get the hex output, rather than needing this pattern. I'm not doing that in this particular PR though.
