Update tracing and fix binary regression
Previous attempts (rust-lang/rust#127316, rust-lang/rust#134770) saw binary size regressions, this was root caused to <https://github.com/tokio-rs/tracing/pull/2553> which changed the behavior of the `max_level_info` feature flag to match the docs (i.e., that flag only applies for debug builds and `release_max_level_info` applies for release builds).
This change bumps the `tracing` version and sets both `max_level_info` and `release_max_level_info` when to match rustc's own `max_level_info`.
