libsupc++: Make the destructor parameter to `__cxa_thread_atexit()` use the `__thiscall` calling convention for i686-w64-mingw32
The mingw-w64 implementations of `__cxa_thread_atexit()` and `__cxa_atexit()` have been
using `__thiscall` since two years ago. Using the default calling convention (which is
`__cdecl`) causes crashes as explained in PR83562.
Calling conventions have no effect on x86_64-w64-mingw32.
