GH-131521: Uses correct build flags for zlib-ng on Windows (GH-131526)

Do not enable AdvancedVectorExtensions2 for all *.c files, so that the resulting binary can be executed on older CPUs, too. Also enable AdvancedVectorExtensions512 where necessary, and add the ClangCL flags required to enable vector extensions.
