Fix CXX initializers

Recent MSVC compiler uses
```c++
using ktl::crt::global_c_handler_t = int(__cdecl*)();
using ktl::crt::global_cxx_handler_t = void(__cdecl*)();

CRTALLOC(".CRT$XIA")
ktl::crt::global_c_handler_t __xi_a[] {nullptr}; // C initializers (first)
CRTALLOC(".CRT$XIZ")
ktl::crt::global_c_handler_t __xi_z[] {nullptr}; // C initializers (last)
CRTALLOC(".CRT$XCA")
ktl::crt::global__cxx_handler_t __xc_a[] {nullptr}; // C++ initializers (first)
CRTALLOC(".CRT$XCZ")
ktl::crt::global_cxx_handler_t __xc_z[] {nullptr}; // C++ initializers (last)
CRTALLOC(".CRT$XPA")
ktl::crt::global_cxx_handler_t __xp_a[] {nullptr}; // C pre-terminators (first)
CRTALLOC(".CRT$XPZ")
ktl::crt::global_cxx_handler_t __xp_z[] {nullptr}; // C pre-terminators (last)
CRTALLOC(".CRT$XTA")
ktl::crt::global_cxx_handler_t __xt_a[] {nullptr}; // C terminators (first)
CRTALLOC(".CRT$XTZ")
ktl::crt::global_cxx_handler_t __xt_z[] {nullptr}; // C terminators (last)
```
instead of [old initializers provided by KTL](https://github.com/DymOK93/KTL/blob/master/runtime/include/crt_runtime.hpp).

Usually MSVC places C++ initializers between `__cxx_ctors_begin__` and `__cxx_ctors_end__` symbols as expected, but with LTO enabled (`/GL` compiler option) includes these symbols in reverse order into a weird `?__cxx_c` section without the initializers themselves:


Reproducible on MSVC 19.28+
