feat(cli): Add `--frozen` flag to error out if lockfile is out of date (#24355)

Closes #18296.

Adds a `--frozen` (alias `--frozen-lockfile`) flag that errors out if
the lockfile is out of date. This is useful for running in CI (where an
out of date lockfile is usually a mistake) or to prevent accidental
changes in dependencies.
