Merge #19445: build: Update msvc build to use ISO standard C++17
2894e94d17
Updates msvc build to use ISO standard C++17. (Aaron Clauson) Pull request description: This PR adds a compiler option to the msvc build to specify ISO C++17 support as discussed in #16684. In order to allow Bitcoin Core to compile with the new option two pre-processor defines are also necessary to avoid an warning (treated as an error) for C++17 deprecated features: - _SILENCE_CXX17_OLD_ALLOCATOR_MEMBERS_DEPRECATION_WARNING - _SILENCE_CXX17_CODECVT_HEADER_DEPRECATION_WARNING For anyone interested a sample compiler message for each of the warnings is shown below: ```` c:\Dev\github\sipsorcery_bitcoin\src\support\allocators\zeroafterfree.h(21,5): error C4996: 'std::allocator<_Ty>::const_pointer': warning STL4010: Various members of std::allocator are deprecated in C++17. Use std::allocator_traits instead of accessing these members directly. You can define _SILENCE_CXX17_OLD_ALLOCATOR_MEMBERS_DEPRECATION_WARNING or _SILENCE_ALL_CXX17_DEPRECATION_WARNINGS to acknowledge that you have received this warning.

(The std::codecvt class template is NOT deprecated.) The C++ Standard doesn't provide equivalent non-deprecated functionality; consider using MultiByteToWideChar() and WideCharToMultiByte() from <Windows.h> instead.
