Subject: refactor: use non-deprecated NSKeyedArchiver APIs

Refs https://chromium-review.googlesource.com/c/chromium/src/+/4628901

Several NSKeyedArchiver methods have been deprecated and replaced as of macOS 10.13:

- unarchiveObjectWithData -> unarchivedObjectOfClass:fromData:error:
- archivedDataWithRootObject -> archivedDataWithRootObject:requiringSecureCoding:error:
