gh-91048: Prevent optimizing away the asyncio debug offsets structure on Windows
To avoid having the debug sections being optimised away by the compilerwe use __attribute__((used)) on gcc and clang but in Windows this isnot supported by the Microsoft compiler and there is no equivalent flag.Unfortunately Windows offers almost no alternative other than exportingthe symbol in the dynamic table or using it somehow.
