refactor(cave): Adjust Cave Overlay to new VirtualRealityPawn, Livelink and inputs
requested to merge vr-vis/VR-Group/unreal-development/david.gilbert/rwth-vr-toolkit:refactor/cave_overlay into dev/5.3
- Spawn CaveOverlay through CaveSetup, which makes the whole system more flexible
- Adjusted CaveSetup to support spawning of Actors only on the Cave
- Removed FPS counter from CaveOverlay - if we really want that, add a separate FPS counter but try to avoid mixing that in the door overlay
- Adjust CaveOverlay to work with the new VirtualRealityPawn (and especially livelink)
- Adjust Input Actions to new input system
- Documented and cleaned the code
Tested in Cave, everything seems to work.
