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.

This commit reworks the C++ language support documentation such that:
1. it contains more up-to-date information regarding the available
features.
2. it makes a clear distinction between the Zephyr C++ subsystem and
the C++ standard library and describe the functionalities they
provide.
