Visual Studio 2013 is finally being EOL'd next April. (https://learn.microsoft.com/en-us/visualstudio/productinfo/vs-servicing#older-versions-of-visual-studio) Let's drop support for it after Ruby 3.3 is released.

If we bump the required version to Visual Studio 2015, we'll get better C99 support and be able to rely on some more standards. Personally I'm excited about snprintf being actually implemented. (https://learn.microsoft.com/en-us/cpp/overview/visual-cpp-language-conformance?view=msvc-170#c-standard-library-features-1)

As support for the argument, CPython requires VS2017 (https://github.com/python/cpython/blob/main/PCbuild/readme.txt) and gnulib requires VS2015(https://www.gnu.org/software/gnulib/manual/html_node/Supported-Platforms.html).

As for snprintf, we avoid system provided implementations not to be affected by locales.
