Convert multi-profile user behavior string to enum and send it to UI.

Multi-profile user behavior is a string value saved in kMultiProfileUserBehavior
prefs which is mapped with a user policy ChromeOsMultiProfileUserBehavior.
This CL converts the string value to a enum and send it to user pod UI.
The kMultiProfileUserBehavior prefs and the cached value in the local state is
not changed(still string value).

commit 820778c575fe891e178b0671a92817a2e54ba197
Author: xiaoyinh <xiaoyinh@chromium.org>

Create Mojo Struct for user information used in login/lock screen.

Introduce a Mojo struct LoginUserInfo for login users which include
basic information ash::mojom::UserInfo and other login/lock
screen specific information.
UserSelectionScreen will populate LoginUserInfo and send it back to lockscreen views.
Compare to the user info we sent to current UI, LoginUserInfo have almost everything except:
1. user's gaiaId, which doesn't seem to be used by current UI.(user_pod_row.js)
2. public session information which doesn't exist on lockscreen.
We might need it for login screen later and I have added a TODO for this.
