Summary [CMake] Add additional check for libatomic

File 'Source/cmake/WebKitCompilerFlags.cmake' contains a small C program to determine whether 'libatomic' should be linked. However, there's a scenario that program doesn't handle. In 32-bit systems, it's necessary to link with libatomic in order to handle data types larger than 8-bytes. An example of an atomic larger than 8-bytes is: `std::atomic<std::optional<double>>`.
