Clean up code formatting and remove unused functions

- Remove unused createGrassGround function from customEnvironment
- Remove commented HemisphericLight code
- Fix deviceDetection to use proper VR detection instead of hardcoded true
- Clean up whitespace in spinner.ts and animatedLineTexture.ts
- Pass empty object to refreshBoundingInfo to match API signature
