When moving apps or shared storage between storage media on FBE devices, we need all users to be unlocked to successfully move the data. This change asks the user to enter the credentials for any locked users as part of the moving/migration wizard flows. To do this we relax Utils.enforceSameOwner() to let us prompt for the credentials of unrelated users, but we carefully only extend this capability to callers interacting with the "internal" activities, which require the MANAGE_USERS permission. Test: builds, boots, users are unlocked before moving Bug: 29923055, 25861755 Change-Id: Ifaeb2557c4f8c4354e1d380eaa0e413768ee239f
