Cleaned up deviceType enum

Summary:
The device type enum was mixing two different concepts (emulator vs physical) and (archived vs not), and we already have a separate `isArchived` field. So cleaned this up to not leak it into sandy.

If anybody can think of any unforeseen consequences of this, lemme know :)
