* Move ctors and init_array from the CPP library
to the kernel library, as this is common for both C
and C++ and it is the kernel who is running it.
* Rename the hidden kconfig option CPP_STATIC_INIT_GNU
STATIC_INIT_GNU instead.
* If STATIC_INIT_GNU is not selected verify there is
constructors left behind.
* Rename common-rom-cpp.ld to common-rom-init.ld
* Rename z_cpp_init_static to z_init_static,
and have the kernel always call it.

For the POSIX architecture we do not define an
empty __cxa_atexit() as it otherwise would
override its host libC counterpart. And this would
both disable the atexit() hooks, and prevent possible
test code global destructors from being registered.

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.
