4445: Add subcommand to run benchmarks r=irevoire a=dureuill
# Pull Request
## Related issue
Not user-facing, no issue
## What does this PR do?
- Adds a new `cargo xtask bench` subcommand that can run one or multiple workload files and report the results to a server
- A workload file is a JSON file with a specific schema
- Refactor our use of the `vergen` crate:
- update to the beta `vergen-git2` crate
- VERGEN_GIT_SEMVER_LIGHTWEIGHT => VERGEN_GIT_DESCRIBE
- factor logic in a single `build-info` crate that is used both by meilisearch and xtask (prevents vergen variables from overriding themselves)
- checked that defining the variables by hand when no git repo is available (docker build case) still works.
- Add CI to run `cargo xtask bench`
