Auto merge of #66981 - michaelwoerister:measureme-0.5.0, r=Mark-Simulacrum

Update measureme crate to 0.5.0

This PR updates the `measureme` self-profiling crate to the latest release. Heads up, this version changes the trace file format, so the `summarize` tool on perf.rlo needs to be updated to 0.5 too.
