[1] Related parts in `m4/curl-functions.m4` and `configure.ac` might
    also be deleted.

[2] Related comment can possibly be deleted in
    `packages/vms/generate_config_vms_h_curl.com`.

[3] There are more instances of this in autotools, but I did not dare to
    touch those. Looked like it's used to detect socket support.

[4] This is necessary for MFC (Microsoft Foundation Class) DLLs to
    force linking MFC components statically to the DLL. `libcurl.dll`
    does not use MFC, so we can delete this define.
    Ref: https://docs.microsoft.com/cpp/build/regular-dlls-statically-linked-to-mfc

Script that can help finding unused settings like above:
```shell

autoheader configure.ac  # generate lib/curl_config.h.in

{
  grep -o -E    'set\([A-Z][A-Z0-9_]{3,}'          CMake/Platforms/WindowsCache.cmake | sed -E 's|set\(||g'
  grep -o -E -h '#define +[A-Z][A-Z0-9_]{3,}'      lib/config-*.h                     | sed -E 's|#define +||g'
  grep -o -E    '#cmakedefine +[A-Z][A-Z0-9_]{3,}' lib/curl_config.h.cmake            | sed -E 's|#cmakedefine +||g'
  grep -o -E    '#undef +[A-Z][A-Z0-9_]{3,}'       lib/curl_config.h.in               | sed -E 's|#undef +||g'
} | sort -u | grep -v -F 'HEADER_CURL_' | while read -r def; do
  c="$(git grep -w -F "${def}" | grep -v -E -c '(/libcurl\.tmpl|^lib/config-|^lib/curl_config\.h\.cmake|^CMakeLists\.txt|^CMake/Platforms/WindowsCache\.cmake|^packages/vms/config_h\.com|^m4/curl-functions\.m4|^acinclude\.m4|^configure\.ac)')"
  if [ "${c}" = '0' ]; then
    echo "${def}"
  fi
done
```
