before this change, we assume that scylla's CMake script includes Seastar's CMake script. but we are going to consume Seastar using its .pc files or its CMake config files instead of including it directly. more over these helper functions are not part of Seastar's public interface. actually the same applies to the `check_headers()` helper, which was adapted from seastar's CheckHeaders.cmake. so to be prepared for this change, let's define these generate helper functions in scylla.
