Rearrange the order that we check for temporary directories in get_temp_dir(). This change causes us to use System temporary directories in preference to WP_CONTENT_DIR, for better windows compatibility, we use win_is_writable() as well. Props simonwheatley and kurtpayne for initial patches, See #20778
