windows: reduce/stop loading DLLs at runtime
- replace dynamic `InitSecurityInterface()` call with early binding and
  link `secur32` system DLL.
  The library and function are available in all supported curl Windows
  targets, meaning WinXP or newer.  Add small hack for mingw32ce to
  make it build.

- detect and use `if_nametoindex()` on Windows when available. Link
  `iphlpapi` system DLL. Requires targeting Vista or newer.
  Replacing the dynamic call and the pre-load optimization for lib3026.
