This commit moves the files under `subsys/cpp` directory to the `lib/cpp` directory because the C++ ABI runtime library and the standard C++ library components are not a "subsystem" (aka. API) in conventional sense and is better described as a "library." Classifying the C++ ABI runtime library and the standard C++ library as "libraries" instead of "subsystems" also better aligns with how the existing C standard library implementation (`lib/libc`) is handled.
