To save configuration time. After this patch, for mingw-w64 and MSVC curl's CMake builds pre-fill almost all type sizes without auto-detection. In most cases this leaves 3 type size auto-detections. Those depend on 64/32-bitness, and `time_t` also depends on CRT and custom options. Old mingw-w64 versions require some extra detections. We recommend v3.0 or newer to avoid them. For Windows CE, this patch pre-fills all type sizes. If this is causing any issue, please report it and disable pre-filling with `-D_CURL_PREFILL=OFF` in the meantime. Cherry-picked from #16394 Closes #16464
