config-win32.h: do not use winsock2 `inet_ntop()`/`inet_pton()`

Syncing winbuild and VS Project File builds with the same fix applied
to cmake and autotools builds earlier.

Also fixes these warnings seen in the VisualStudioSolution (VS2013) job
on AppVeyor CI:
```
lib\hostip.c(148): warning C4090: 'function' : different 'const' qualifiers
lib\hostip.c(155): warning C4090: 'function' : different 'const' qualifiers
```
Ref: https://ci.appveyor.com/project/curlorg/curl/builds/52470650/job/gslnjrdxnd8b9mtv#L180

Went unnoticed because warnings are not promoted to error in these builds.
winbuild CI jobs did not hit this warning for some reason.

Follow-up to 8537a5b0bcf4565551774c2b2375c49767e405a7 #16577
Closes #18045
