fix(vitis): replace absolute paths with relative paths for cross-platform compatibility

- Replace hardcoded /home/ly0kos/ paths in .prj, .sprj, and platform.spr
  with relative paths so the project can be cloned and opened on any machine
- Remove RemoteSystemsTempFiles/.project from git (IDE temp file)
- Add .gitignore at Vitis root to exclude .metadata/, RemoteSystemsTempFiles/,
  IDE.log, *.log, and .analytics/
- Update NewInstCal_bsp/.gitignore to stop ignoring /export/ (needed for xpfm)
- Add .gitattributes for consistent line ending handling across platforms
