On Windows, ctypes does no longer check the stack before and after

calling a foreign function.  This allows to use the unmodified libffi
library.

Remove most files from _ctypes/libffi_msvc, only two include files
stay (updated from _ctypes/libffi/...).  Other files are used in the
cross-platform _ctypes/libffi directory.
