refactor: replace custom Quote parsing with library version

- Removed custom `Quote` structure and parsing logic in `teepot/src/sgx/mod.rs`.
- Updated references to use the library-provided `Quote` methods, such as `Quote::parse` and `get_report_data`.
- Simplified code and reduced redundancy by leveraging existing library functionality.
