Revert "Adding Control Flow guard to Windows Builds"

Browse Source 
Reasons:
- The patch was missing the linker flag /guard:cf
  As a result no binary with CFG was ever built
- /guard:cf is incompatible with NASM
  If the linker flag is added, the resulting binary fails with this exception:
  Unhandled exception at 0x00007FFFB8B93C90 (ntdll.dll) in openssl.exe: Indirect call guard check detected invalid control transfer.
