Remove socket code from PIEEGBoard and restructure periphery inclusion

- Removed socket-related code from PIEEGBoard to adhere to high-level API usage for data streaming.
- Moved the c_periphery library to the third_party folder.
- Updated CMakeLists and build.cmake to conditionally include and link periphery only when needed.
- Removed unnecessary 'c' and 'm' libraries from the target_link_libraries.
- Removed the emulator script and unnecessary examples from the PR.
