Implemented system tray UI for new account management.

* Added new mode in TrayUser for the case when new account management is
  enabled (--new-profile-management flag). In fact TrayUser is now supporting
  four different modes, depending of states of |multi-profiles| flag and
  |new-profile-management| flag.
* Massive refactoring were made in tray_user.cc to isolate UserCardView
  creation in separate class and make code more clear.
* UI for the cases when new account management is disabled remained without
  changes.

Known issues:
* There are no tests for new UI. Hopefully old UI is covered by tests already.
* New UI is not accessible yet.
* Stub implementation of UserAccountsDelegate is used for backend.
