Standardize error handling and output across all examples (NVIDIA#1678)

- Remove success/completion fluff messages ("done!", "passed", etc.)
- Use sys.exit(1) instead of sys.exit(0) for unsupported configurations
- Send skip/warning/error messages to stderr
- Replace user-facing assert with proper checks
- Standardize sys.exit(-1) to sys.exit(1)
