nmlgc ff667d35f2 SDL_mslibc: Implement _ftoul2_legacy() 
cl.exe versions ≥v19.41 call this builtin for double → uint64_t
conversions on x86. SDL currently needs such conversions in:

* MainCallbackRateHintChanged()
* SDL_PrintFloat()
* WIN_ApplyWindowProgress()

This seems enough to justify implementing this function rather than
trying to work around it, as it was done in sdl12-compat:

	https://github.com/libsdl-org/sdl12-compat/issues/352

This implementation was taken from ReactOS:

	https://git.reactos.org/?p=reactos.git;a=commitdiff;h=f637e6b809adb5e0ae420ef4f80c73b19172a2e7

Passes the stdlib testautomation, and also matches the behavior of
Microsoft's 64-bit libc for the currently implementation-defined case
of calling SDL_PrintFloat() with values >SDL_MAX_UINT64.
