Cod 1364 runner sample without splitting perfdata

[not-matthias]

Changes in this PR:

• Create runner-shared crate which is used in the perf-parser crate
• Add support for the perf v2 format
• Add SetVersion command to detect incompatible integrations

[Copilot]

Pull Request Overview

This PR refactors the perf runner to use a single perf.data file instead of splitting it across multiple files, and extracts shared data structures into a new runner-shared crate.

• Consolidates perf data collection into a single perf.data file rather than splitting by process
• Moves shared data structures (UnwindData, PerfMetadata, FIFO commands) to new runner-shared crate
• Updates the benchmark tracking mechanism to use timestamps instead of per-process ordering

It's weird you had to fix the clippy issues since we have this in the recommit hooks:

      - id: clippy
        args: [--all-targets, --, -D, warnings]

Did the rust version or anything else change?

Ahh, I think I'm using a newer Rust version. Should I revert the commit?

Anyway we'd have to do those changes at some point so we can keep it. Are you using rustup? Normally it picks up the rust-toolchain.toml automatically
