Refactor CMake configuration and enhance VPN client architecture

- Updated CMakeLists.txt to support multiple build options for drivers and cores, including HevSocks5, Tun2Socks, SingBox, LibXray, and V2Ray.
- Introduced a modular architecture with separate driver and core configurations.
- Enhanced README.md to reflect new architecture and usage examples.
- Renamed Android project to 'flutter_vpn_engine' for consistency.
- Updated header files to define new enums and structures for driver and core configurations.
- Implemented factory methods for creating drivers and cores in the VPN client engine.
