Unlock non-secure users automatically (2/2)

...while moving apps or media content from internal storage to
adopted storage and vice-versa.
Currently, for FBE enabled devices, whenever move is triggered for
either app or media content, there is a prompt for user to enter their
lockscreen credentials in order to unlock storage if the user has one.
But if the user does not have a lockscreen credential set and is not
running,the wizard page is stuck. This leads to a bad user experience.

StorageWizardMigrateConfirm & StorageWizardMoveConfirm uses
ChooseLockSettingsHelper to launch the authentication method set by the
user in order to unlock the storage. But, it does not handle the
use-case where user has no authentication set and not running, causing
return to the wizard activities, thus blocking the flow. This CL solves
the issue by, checking if the user is not secure, attempt unlock the
storage otherwise prompt the user to unlock.

Bug: 305978187
Test: manual
Steps
 1. Create multiple users with atleast one user with an authentication
   method setup and one without authentication (apart from system user)
 2. Install same apps for all users and also add some content to the
    media storage.
 3. Format an SD Card as adopted.
 4. Attempt to move content.
 5. Check that the wizard is not stuck and it is prompting the locked
    users to authenticate.
 6. Reboot
 7. After reboot, Go to Settings > All Apps > app_name
    > Storage & Cache
 8. Tap on "Change" under Storage and Select Adopted storage.
 9. Check the same as Step#5
