Move types.h #undefs for wincrypt.h compatibility

+ Always undef the symbols that may have been #define-d
  by wincrypt.h after the first inclusion of types.h to
  avoid errors from wincrypt.h symbols being used to
  compile OpenSSL code
+ Also need to remove #pragma once for this approach to work
+ Define WINCRYPT_USE_SYMBOL_PREFIX to enable wincrypt
  symbol prefix at some point in future

Fixes #9981
