Add OpenSSL dependency to CMakeLists.txt files for C and C++ projects

- Include `find_package(OpenSSL REQUIRED)` to ensure OpenSSL is available.
- Link the `bittorrent` executable with OpenSSL's Crypto library across all relevant CMakeLists.txt files in compiled_starters, solutions, and starter_templates.
