Rollup merge of rust-lang#142356 - Stypox:fix-enter_trace_span, r=RalfJung

Fix enter_trace_span!() using wrong $crate paths

This is a followup to rust-lang#140972, where I made a silly mistake and forgot to update `$crate::interpret::tracing_utils::...` to `$crate::interpret::util::...` inside the macro after moving the referenced code from `tracing_utils.rs` to `util.rs`. Sorry about this.
