Subject: [PATCH] build: tidy-ups around `inet_pton`

- cmake: make the `inet_pton`/`inet_ntop` detection codepath explicit
  for WinCE. To not rely on an empty `HAVE_WIN32_WINNT`.

- tests/server/mqttd: drop `inet_pton` header and lib source.

- tests/server: move `inet_pton` lib source to a variable.

Closes #16563
