Added option to pre-create user templates to optimize first user creation time.
Initial user creation is slow because the system must prepare per-user data (like storage and
permissions) whose cost is proportional to the number of pre-installed apps. On automovive's
reference implementation, it can take more than 10s, which is a bad user experience.
This change lets OEMs pre-create some users , so that high initial-creation cost is "paid" during
the initial boot. On automotive, it improves the creation of an additional user (or guest user)
in about 7s (from ~17s to 9s).
