- UPDATE - revert migration of logs

- UPDATE - use derive on LinkRlibError enum

- [Gardening] UPDATE - alphabetically sort fluent_messages

- UPDATE - use PathBuf and unify both AddNativeLibrary to use Display (which is what PathBuf uses when conforming to IntoDiagnosticArg)

- UPDATE - fluent messages sort after rebase
