Allow setting User Restrictions per user type

FULL and PROFILE user types now have their default restrictions
delineated in UserTypeFactory. The restrictions for these user types can
be customized in config_user_types, along with the other user type
customization.

Note: even though FULL user types can now be customized, the only
supported customization is user restrictions. Moreover, new FULL user
types cannot be defined.

This cl also has the following repercussions:
-When a user is created (but not yet started), the applied restrictions
are not propagated as an update (prior to this, the restrictions for new
users - other than guest - were set via setUserRestriction, which did
more than just store the data). When the user is started, the
restrictions will still be propagated.

-When a user is created via adb, its default restrictions are applied.
Previously this was not the case except for guest users.

-When an Admin user is created/set, it is now the callers responsibility to
adjust its restrictions. UserManager will no longer automatically remove
the DISALLOW_SMS/DISALLOW_OUTGOING_CALLS restrictions for Admins.

Also note that Restricted Users have additional hardcoded restrictions,
indepent of this cl.
