update(cmake): Build zlib using CMake on Windows

Build zlib using CMake on Windows instead of nmake. The nmakefile passes "-base:0x5A4C0000" to the linker, which is too small on Arm64 and not really needed or wanted on any platform these days. madler/zlib#325 Signed-off-by: Gerald Combs <[email protected]>
