Fix: Make PC return recovery title-specific for Little Nightmares 3

The PC < 0x1000 recovery mechanism introduced in commit fbb4f5c0
was causing issues for other games. This change restricts the recovery
to only apply when the title ID matches Little Nightmares 3.

- Add LittleNightmares3 title ID constant to title_ids.h
- Check program ID before applying PC return recovery in physical_core.cpp
- Recovery now only triggers for Little Nightmares 3 (010066101A55A800)
  to avoid affecting other games

Fixes issues caused by the general PC return recovery in other titles.
