Winner's Path modifications

- Added a Strength Switch puzzle to floor 2, which took an unhealthy amount of time to do. This is possible in GSC but requires a lot of extremely hacky solutions. There is a glitch that causes the boulder not to move once on the switch if you reload the map but I have been doing this for 3-4 hours, shush.
- Added a depressed switch tile to accomodate the new functionality.
- New switch collision type for boulder puzzles.
- Removed a lot of unused/unreferenced stuff that isn't necessary in Crystal to save space.
