Summary:
Adds a new script that runs Yarn with --frozen-lockfile, and fails if Yarn finds the lockfile is out of sync.
Keeping the lockfile in sync with package.json will ensure our internal open source tests can run offline, as our offline mirror is updated whenever the lockfile changes.
Reverted yarn.lock to https://raw.githubusercontent.com/facebook/react-native/6eeff75849c9b8bf91592c1b7906b4dab8fba518/yarn.lock, then ran `scripts/circleci/validate_yarn_lockfile.sh`, and verified the script failed as expected.
I then ran Yarn without the --frozen-lockfile flag, and reran the validation script. This time, the script finished successfully.
