Introduces two new UserInfo flags: SYSTEM - refers to the system user, i.e. user 0. Although UserManagerService already knows which user is the system, this flag will be useful in other contexts. FULL - refers to a non-profile human user. Right now, for every user, one of the following flag combos are true: SYSTEM (user 0 on a headless-user-0 device) SYSTEM | FULL (user 0 on a regular device) FULL (secondary user) MANAGED_PROFILE (profile users) Test: Manual verification via "pm list users" of new flags when adding a new user Test: Manual verification via "pm list users" of new flags for pre-existing users Test: Later cls will test the functionality as it is introduced Bug: 134605778 Change-Id: Ife92bfa8a91cc4567d825da8e6a1b3894b088b22
