Subject: [PATCH] Fix build problems due to "missing" newer MSW APIs with MinGW
 5.3.0

Set WINVER/_WIN32_WINNT ourselves before letting MinGW to set them to very low
values corresponding to Windows 2000 on its own and preventing our code from
seeing any later additions to the Windows API, such as AttachConsole()
function used in src/msw/app.cpp.

Closes #17677.
