[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.

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 '#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)')"
