 - Change C-runtime from MSVCRT to UCRT of x64 version.
   See the feature request here: https://bugs.ruby-lang.org/issues/17845

   There are several platform strings that change with the new release.
   They are summarized here: https://github.com/ruby/ruby/pull/4599
   In particular the ruby and gem platform is now "x64-mingw-ucrt" instead of "x64-mingw32" and the MSYS2 package prefix is now `mingw-w64-ucrt-x86_64-`.
 - No longer require fiddle before booting Rubygems, but use the new C-extension "win32/dll_directory".
