To avoid redefining the `fstat` system symbol, and to clarify `struct_stat` is a curl symbol. - introduce `curlx_fstat()` macro and use it. - rename `struct_stat` to `curl_struct_stat`. Also: - tests: replace direct `curlx_win32_stat()` call with `curlx_stat()`. - checksrc: disallow direct `_fstati64` and `fstat()` calls, except in examples. Closes #20496
