[libconfig] fix compilation errors on macos (#19374)

* remove "find_path(STDINT_H stdint.h)". On clang/macos, this picks up the kernel headers version of stdint.h, instead of the C standard library, breaking compilation
* only define YY_NO_UNISTD_H and YY_USE_CONST on Windows, like the upstream CMakeLists.txt
* set the C standard to C99, like the upstream CMakeLists.txt
* update to 1.7.3
* remove the "fail" line from ci.baseline.txt
* run ./vcpkg x-add-version --all to update metadata files
* reset port-version
