This commit relocates the "C++ ABI library" components such as global constructor/destructor and initialiser handlers to a dedicated directory, `lib/cpp/abi`, in order to provide a clear separation between the C++ ABI/runtime library and the standard C++ library components. Note that the Zephyr C++ ABI library currently implements the GNU/GCC C++ ABI, which is the de-facto standard ABI used by many compilers including Clang -- it may be necessary to sub-divide the `lib/cpp/abi` into `lib/cpp/abi/gnu` and `lib/cpp/abi/someotherabi` in the future when adding the support for a C++ compiler that expects an ABI vastly different from the GNU C++ ABI.
