Subject: [PATCH] configure: link `-lcrypt32` instead of `-lm` for wolfSSL on
 Windows

Syncing it with CMake/FindWolfSSL.

`-lm` is not needed on Windows. As of mingw-w64 14.0.0 it's offered as
a dummy library; in such case it wasn't causing an actual issue.
`-lcryp32` is necessary when linking wolfSSL statically.

Ref: #22249

Closes #22251
