feat: add PC Engine / TurboGrafx-16 support

PC Engine HuCard games (.pce files) now import and sync correctly
instead of being detected as Arcade.

---
Added PC Engine to system registry with RetroAchievements console
ID mapping. CD games (.chd) will come later since they need
folder-based detection.

Fixes #101
