[PATCH] msvcrt: Add __fpe_flt_rounds stub.

Fixes https://bugs.winehq.org/show_bug.cgi?id=40765 - with this patch,
python.exe starts and can interpret basic commands.

The only thing that MSDN says about this function is that it is "used to
implement the CRT and the C++ Standard Library".[1] The function
prototype can be found in float.h in the Windows 10 SDK.
