[Rust] WIP: Replace log with tracing

- Added more documentation
- Replaced global named logger for plugins, fixing the issue when the CU has multiple (e.g. statically linked demo)
- Simplified some misc code

This is a breaking change, but I believe there is no better time to make it, we cannot continue to use the `log` crate, it is too limited for our needs.
