[identity] Store device code version and login date

Summary:
For primary device "migration", we need to store device code version along with the timestam at which access token was generated. This is required for ENG-5841.

Depends on D10397

Test Plan:
Registered a new user and verified that the device code version and login date are stored in the database.
Logged in as that user but with a new device, made sure the data is stored for the new device too.
