hle/service/acc: Implement acc:e, acc:e:u1, acc:e:u2, and dauth:0 services

- Add acc:e service with full account management functionality
- Add acc:e:u1 service (minimal implementation)
- Add acc:e:u2 service with extended functionality including PIN code support
- Add dauth:0 device authentication service
- Update acc_su function mappings to match newer firmware versions
- Move TrySelectUserWithoutInteraction from ID 51 to 52 with deprecated fallback

These services provide additional account management interfaces used by
newer Switch firmware versions and some games that require extended
account functionality.
